Elasticsearch APIs use key-based authentication. You must create an API key and use the encoded value in the request header. For example:
curl -X GET "${ES_URL}/_cat/indices?v=true" \
-H "Authorization: ApiKey ${API_KEY}"
To get API keys for the Elasticsearch endpoint (${ES_URL}) for a project, refer to Connect to your Elasticsearch Serverless endpoint.
The associated data stream is also deleted.
The name of the analytics collection to be deleted
curl \
--request DELETE http://api.example.com/_application/analytics/{name} \

}The compact and aligned text (CAT) APIs aim are intended only for human consumption using the Kibana console or command line. They are not intended for use by applications. For application consumption, it's recommend to use a corresponding JSON API.
All the cat commands accept a query string parameter help to see all the headers and info they provide, and the /_cat command alone lists all the available commands.
Get the cluster's index aliases, including filter and routing information. This API does not return data stream aliases.
IMPORTANT: CAT APIs are only intended for human consumption using the command line or the Kibana console. They are not intended for use by applications. For application consumption, use the aliases API.
A comma-separated list of aliases to retrieve. Supports wildcards (*). To retrieve all aliases, omit this parameter or use * or _all.
List of columns to appear in the response. Supports simple wildcards.
List of columns that determine how the table should be sorted.
Sorting defaults to ascending and can be changed by setting :asc
or :desc as a suffix to the column name.
The type of index that wildcard patterns can match.
If the request can target data streams, this argument determines whether wildcard expressions match hidden data streams.
It supports comma-separated values, such as open,hidden.
The period to wait for a connection to the master node.
If the master node is not available before the timeout expires, the request fails and returns an error.
To indicated that the request should never timeout, you can set it to -1.

}Converts an index alias to a data stream.
You must have a matching index template that is data stream enabled.
The alias must meet the following criteria:
The alias must have a write index;
All indices for the alias must have a @timestamp field mapping of a date or date_nanos field type;
The alias must not have any filters;
The alias must not use custom routing.
If successful, the request removes the alias and creates a data stream with the same name.
The indices for the alias become hidden backing indices for the stream.
The write index for the alias becomes the write index for the stream.
Name of the index alias to convert to a data stream.
Period to wait for a connection to the master node. If no response is received before the timeout expires, the request fails and returns an error.

This reduces overhead and can greatly increase indexing speed.
If the Elasticsearch security features are enabled, you must have the following index privileges for the target data stream, index, or index alias:
create action, you must have the create_doc, create, index, or write index privilege. Data streams support only the create action.index action, you must have the create, index, or write index privilege.delete action, you must have the delete or write index privilege.update action, you must have the index or write index privilege.auto_configure, create_index, or manage index privilege.refresh parameter, you must have the maintenance or manage index privilege.Automatic data stream creation requires a matching index template with data stream enabled.
The actions are specified in the request body using a newline delimited JSON (NDJSON) structure:
action_and_meta_data\n
optional_source\n
action_and_meta_data\n
optional_source\n
....
action_and_meta_data\n
optional_source\n
The index and create actions expect a source on the next line and have the same semantics as the op_type parameter in the standard index API.
A create action fails if a document with the same ID already exists in the target
An index action adds or replaces a document as necessary.
NOTE: Data streams support only the create action.
To update or delete a document in a data stream, you must target the backing index containing the document.
An update action expects that the partial doc, upsert, and script and its options are specified on the next line.
A delete action does not expect a source on the next line and has the same semantics as the standard delete API.
NOTE: The final line of data must end with a newline character (\n).
Each newline character may be preceded by a carriage return (\r).
When sending NDJSON data to the _bulk endpoint, use a Content-Type header of application/json or application/x-ndjson.
Because this format uses literal newline characters (\n) as delimiters, make sure that the JSON actions and sources are not pretty printed.
If you provide a target in the request path, it is used for any actions that don't explicitly specify an _index argument.
A note on the format: the idea here is to make processing as fast as possible.
As some of the actions are redirected to other shards on other nodes, only action_meta_data is parsed on the receiving node side.
Client libraries using this protocol should try and strive to do something similar on the client side, and reduce buffering as much as possible.
There is no "correct" number of actions to perform in a single bulk request. Experiment with different settings to find the optimal size for your particular workload. Note that Elasticsearch limits the maximum size of a HTTP request to 100mb by default so clients must ensure that no request exceeds this size. It is not possible to index a single document that exceeds the size limit, so you must pre-process any such documents into smaller pieces before sending them to Elasticsearch. For instance, split documents into pages or chapters before indexing them, or store raw binary data in a system outside Elasticsearch and replace the raw data with a link to the external system in the documents that you send to Elasticsearch.
Client suppport for bulk requests
Some of the officially supported clients provide helpers to assist with bulk requests and reindexing:
esutil.BulkIndexerSearch::Elasticsearch::Client::5_0::Bulk and Search::Elasticsearch::Client::5_0::Scrollelasticsearch.helpers.*client.helpers.*BulkAllObservableSubmitting bulk requests with cURL
If you're providing text file input to curl, you must use the --data-binary flag instead of plain -d.
The latter doesn't preserve newlines. For example:
$ cat requests
{ "index" : { "_index" : "test", "_id" : "1" } }
{ "field1" : "value1" }
$ curl -s -H "Content-Type: application/x-ndjson" -XPOST localhost:9200/_bulk --data-binary "@requests"; echo
{"took":7, "errors": false, "items":[{"index":{"_index":"test","_id":"1","_version":1,"result":"created","forced_refresh":false}}]}
Optimistic concurrency control
Each index and delete action within a bulk API call may include the if_seq_no and if_primary_term parameters in their respective action and meta data lines.
The if_seq_no and if_primary_term parameters control how operations are run, based on the last modification to existing documents. See Optimistic concurrency control for more details.
Versioning
Each bulk item can include the version value using the version field.
It automatically follows the behavior of the index or delete operation based on the _version mapping.
It also support the version_type.
Routing
Each bulk item can include the routing value using the routing field.
It automatically follows the behavior of the index or delete operation based on the _routing mapping.
NOTE: Data streams do not support custom routing unless they were created with the allow_custom_routing setting enabled in the template.
Wait for active shards
When making bulk calls, you can set the wait_for_active_shards parameter to require a minimum number of shard copies to be active before starting to process the bulk request.
Refresh
Control when the changes made by this request are visible to search.
NOTE: Only the shards that receive the bulk request will be affected by refresh.
Imagine a _bulk?refresh=wait_for request with three documents in it that happen to be routed to different shards in an index with five shards.
The request will only wait for those three shards to refresh.
The other two shards that make up the index do not participate in the _bulk request at all.
True or false if to include the document source in the error message in case of parsing errors.
If true, the response will include the ingest pipelines that were run for each index or create.
The pipeline identifier to use to preprocess incoming documents.
If the index has a default ingest pipeline specified, setting the value to _none turns off the default ingest pipeline for this request.
If a final pipeline is configured, it will always run regardless of the value of this parameter.
If true, Elasticsearch refreshes the affected shards to make this operation visible to search.
If wait_for, wait for a refresh to make this operation visible to search.
If false, do nothing with refreshes.
Valid values: true, false, wait_for.
Values are true, false, or wait_for.
A custom value that is used to route operations to a specific shard.
Indicates whether to return the _source field (true or false) or contains a list of fields to return.
A comma-separated list of source fields to exclude from the response.
You can also use this parameter to exclude fields from the subset specified in _source_includes query parameter.
If the _source parameter is false, this parameter is ignored.
A comma-separated list of source fields to include in the response.
If this parameter is specified, only these source fields are returned.
You can exclude fields from this subset using the _source_excludes query parameter.
If the _source parameter is false, this parameter is ignored.
The period each action waits for the following operations: automatic index creation, dynamic mapping updates, and waiting for active shards.
The default is 1m (one minute), which guarantees Elasticsearch waits for at least the timeout before failing.
The actual wait time could be longer, particularly when multiple waits occur.
The number of shard copies that must be active before proceeding with the operation.
Set to all or any positive integer up to the total number of shards in the index (number_of_replicas+1).
The default is 1, which waits for each primary shard to be active.
If true, the request's actions must target an index alias.
If true, the request's actions must target a data stream (existing or to be created).

}Perform multiple index, create, delete, and update actions in a single request.
This reduces overhead and can greatly increase indexing speed.
If the Elasticsearch security features are enabled, you must have the following index privileges for the target data stream, index, or index alias:
create action, you must have the create_doc, create, index, or write index privilege. Data streams support only the create action.index action, you must have the create, index, or write index privilege.delete action, you must have the delete or write index privilege.update action, you must have the index or write index privilege.auto_configure, create_index, or manage index privilege.refresh parameter, you must have the maintenance or manage index privilege.Automatic data stream creation requires a matching index template with data stream enabled.
The actions are specified in the request body using a newline delimited JSON (NDJSON) structure:
action_and_meta_data\n
optional_source\n
action_and_meta_data\n
optional_source\n
....
action_and_meta_data\n
optional_source\n
The index and create actions expect a source on the next line and have the same semantics as the op_type parameter in the standard index API.
A create action fails if a document with the same ID already exists in the target
An index action adds or replaces a document as necessary.
NOTE: Data streams support only the create action.
To update or delete a document in a data stream, you must target the backing index containing the document.
An update action expects that the partial doc, upsert, and script and its options are specified on the next line.
A delete action does not expect a source on the next line and has the same semantics as the standard delete API.
NOTE: The final line of data must end with a newline character (\n).
Each newline character may be preceded by a carriage return (\r).
When sending NDJSON data to the _bulk endpoint, use a Content-Type header of application/json or application/x-ndjson.
Because this format uses literal newline characters (\n) as delimiters, make sure that the JSON actions and sources are not pretty printed.
If you provide a target in the request path, it is used for any actions that don't explicitly specify an _index argument.
A note on the format: the idea here is to make processing as fast as possible.
As some of the actions are redirected to other shards on other nodes, only action_meta_data is parsed on the receiving node side.
Client libraries using this protocol should try and strive to do something similar on the client side, and reduce buffering as much as possible.
There is no "correct" number of actions to perform in a single bulk request. Experiment with different settings to find the optimal size for your particular workload. Note that Elasticsearch limits the maximum size of a HTTP request to 100mb by default so clients must ensure that no request exceeds this size. It is not possible to index a single document that exceeds the size limit, so you must pre-process any such documents into smaller pieces before sending them to Elasticsearch. For instance, split documents into pages or chapters before indexing them, or store raw binary data in a system outside Elasticsearch and replace the raw data with a link to the external system in the documents that you send to Elasticsearch.
Client suppport for bulk requests
Some of the officially supported clients provide helpers to assist with bulk requests and reindexing:
esutil.BulkIndexerSearch::Elasticsearch::Client::5_0::Bulk and Search::Elasticsearch::Client::5_0::Scrollelasticsearch.helpers.*client.helpers.*BulkAllObservableSubmitting bulk requests with cURL
If you're providing text file input to curl, you must use the --data-binary flag instead of plain -d.
The latter doesn't preserve newlines. For example:
$ cat requests
{ "index" : { "_index" : "test", "_id" : "1" } }
{ "field1" : "value1" }
$ curl -s -H "Content-Type: application/x-ndjson" -XPOST localhost:9200/_bulk --data-binary "@requests"; echo
{"took":7, "errors": false, "items":[{"index":{"_index":"test","_id":"1","_version":1,"result":"created","forced_refresh":false}}]}
Optimistic concurrency control
Each index and delete action within a bulk API call may include the if_seq_no and if_primary_term parameters in their respective action and meta data lines.
The if_seq_no and if_primary_term parameters control how operations are run, based on the last modification to existing documents. See Optimistic concurrency control for more details.
Versioning
Each bulk item can include the version value using the version field.
It automatically follows the behavior of the index or delete operation based on the _version mapping.
It also support the version_type.
Routing
Each bulk item can include the routing value using the routing field.
It automatically follows the behavior of the index or delete operation based on the _routing mapping.
NOTE: Data streams do not support custom routing unless they were created with the allow_custom_routing setting enabled in the template.
Wait for active shards
When making bulk calls, you can set the wait_for_active_shards parameter to require a minimum number of shard copies to be active before starting to process the bulk request.
Refresh
Control when the changes made by this request are visible to search.
NOTE: Only the shards that receive the bulk request will be affected by refresh.
Imagine a _bulk?refresh=wait_for request with three documents in it that happen to be routed to different shards in an index with five shards.
The request will only wait for those three shards to refresh.
The other two shards that make up the index do not participate in the _bulk request at all.
The name of the data stream, index, or index alias to perform bulk actions on.
True or false if to include the document source in the error message in case of parsing errors.
If true, the response will include the ingest pipelines that were run for each index or create.
The pipeline identifier to use to preprocess incoming documents.
If the index has a default ingest pipeline specified, setting the value to _none turns off the default ingest pipeline for this request.
If a final pipeline is configured, it will always run regardless of the value of this parameter.
If true, Elasticsearch refreshes the affected shards to make this operation visible to search.
If wait_for, wait for a refresh to make this operation visible to search.
If false, do nothing with refreshes.
Valid values: true, false, wait_for.
Values are true, false, or wait_for.
A custom value that is used to route operations to a specific shard.
Indicates whether to return the _source field (true or false) or contains a list of fields to return.
A comma-separated list of source fields to exclude from the response.
You can also use this parameter to exclude fields from the subset specified in _source_includes query parameter.
If the _source parameter is false, this parameter is ignored.
A comma-separated list of source fields to include in the response.
If this parameter is specified, only these source fields are returned.
You can exclude fields from this subset using the _source_excludes query parameter.
If the _source parameter is false, this parameter is ignored.
The period each action waits for the following operations: automatic index creation, dynamic mapping updates, and waiting for active shards.
The default is 1m (one minute), which guarantees Elasticsearch waits for at least the timeout before failing.
The actual wait time could be longer, particularly when multiple waits occur.
The number of shard copies that must be active before proceeding with the operation.
Set to all or any positive integer up to the total number of shards in the index (number_of_replicas+1).
The default is 1, which waits for each primary shard to be active.
If true, the request's actions must target an index alias.
If true, the request's actions must target a data stream (existing or to be created).

}Add a JSON document to the specified data stream or index and make it searchable. If the target is an index and the document already exists, the request updates the document and increments its version.
NOTE: You cannot use this API to send update requests for existing documents in a data stream.
If the Elasticsearch security features are enabled, you must have the following index privileges for the target data stream, index, or index alias:
PUT /<target>/_doc/<_id> request format, you must have the create, index, or write index privilege.POST /<target>/_doc/ request format, you must have the create_doc, create, index, or write index privilege.auto_configure, create_index, or manage index privilege.Automatic data stream creation requires a matching index template with data stream enabled.
NOTE: Replica shards might not all be started when an indexing operation returns successfully.
By default, only the primary is required. Set wait_for_active_shards to change this default behavior.
Automatically create data streams and indices
If the request's target doesn't exist and matches an index template with a data_stream definition, the index operation automatically creates the data stream.
If the target doesn't exist and doesn't match a data stream template, the operation automatically creates the index and applies any matching index templates.
NOTE: Elasticsearch includes several built-in index templates. To avoid naming collisions with these templates, refer to index pattern documentation.
If no mapping exists, the index operation creates a dynamic mapping. By default, new fields and objects are automatically added to the mapping if needed.
Automatic index creation is controlled by the action.auto_create_index setting.
If it is true, any index can be created automatically.
You can modify this setting to explicitly allow or block automatic creation of indices that match specified patterns or set it to false to turn off automatic index creation entirely.
Specify a comma-separated list of patterns you want to allow or prefix each pattern with + or - to indicate whether it should be allowed or blocked.
When a list is specified, the default behaviour is to disallow.
NOTE: The action.auto_create_index setting affects the automatic creation of indices only.
It does not affect the creation of data streams.
Optimistic concurrency control
Index operations can be made conditional and only be performed if the last modification to the document was assigned the sequence number and primary term specified by the if_seq_no and if_primary_term parameters.
If a mismatch is detected, the operation will result in a VersionConflictException and a status code of 409.
Routing
By default, shard placement — or routing — is controlled by using a hash of the document's ID value.
For more explicit control, the value fed into the hash function used by the router can be directly specified on a per-operation basis using the routing parameter.
When setting up explicit mapping, you can also use the _routing field to direct the index operation to extract the routing value from the document itself.
This does come at the (very minimal) cost of an additional document parsing pass.
If the _routing mapping is defined and set to be required, the index operation will fail if no routing value is provided or extracted.
NOTE: Data streams do not support custom routing unless they were created with the allow_custom_routing setting enabled in the template.
Distributed
The index operation is directed to the primary shard based on its route and performed on the actual node containing this shard. After the primary shard completes the operation, if needed, the update is distributed to applicable replicas.
Active shards
To improve the resiliency of writes to the system, indexing operations can be configured to wait for a certain number of active shard copies before proceeding with the operation.
If the requisite number of active shard copies are not available, then the write operation must wait and retry, until either the requisite shard copies have started or a timeout occurs.
By default, write operations only wait for the primary shards to be active before proceeding (that is to say wait_for_active_shards is 1).
This default can be overridden in the index settings dynamically by setting index.write.wait_for_active_shards.
To alter this behavior per operation, use the wait_for_active_shards request parameter.
Valid values are all or any positive integer up to the total number of configured copies per shard in the index (which is number_of_replicas+1).
Specifying a negative value or a number greater than the number of shard copies will throw an error.
For example, suppose you have a cluster of three nodes, A, B, and C and you create an index index with the number of replicas set to 3 (resulting in 4 shard copies, one more copy than there are nodes).
If you attempt an indexing operation, by default the operation will only ensure the primary copy of each shard is available before proceeding.
This means that even if B and C went down and A hosted the primary shard copies, the indexing operation would still proceed with only one copy of the data.
If wait_for_active_shards is set on the request to 3 (and all three nodes are up), the indexing operation will require 3 active shard copies before proceeding.
This requirement should be met because there are 3 active nodes in the cluster, each one holding a copy of the shard.
However, if you set wait_for_active_shards to all (or to 4, which is the same in this situation), the indexing operation will not proceed as you do not have all 4 copies of each shard active in the index.
The operation will timeout unless a new node is brought up in the cluster to host the fourth copy of the shard.
It is important to note that this setting greatly reduces the chances of the write operation not writing to the requisite number of shard copies, but it does not completely eliminate the possibility, because this check occurs before the write operation starts.
After the write operation is underway, it is still possible for replication to fail on any number of shard copies but still succeed on the primary.
The _shards section of the API response reveals the number of shard copies on which replication succeeded and failed.
No operation (noop) updates
When updating a document by using this API, a new version of the document is always created even if the document hasn't changed.
If this isn't acceptable use the _update API with detect_noop set to true.
The detect_noop option isn't available on this API because it doesn’t fetch the old source and isn't able to compare it against the new source.
There isn't a definitive rule for when noop updates aren't acceptable. It's a combination of lots of factors like how frequently your data source sends updates that are actually noops and how many queries per second Elasticsearch runs on the shard receiving the updates.
Versioning
Each indexed document is given a version number.
By default, internal versioning is used that starts at 1 and increments with each update, deletes included.
Optionally, the version number can be set to an external value (for example, if maintained in a database).
To enable this functionality, version_type should be set to external.
The value provided must be a numeric, long value greater than or equal to 0, and less than around 9.2e+18.
NOTE: Versioning is completely real time, and is not affected by the near real time aspects of search operations. If no version is provided, the operation runs without any version checks.
When using the external version type, the system checks to see if the version number passed to the index request is greater than the version of the currently stored document. If true, the document will be indexed and the new version number used. If the value provided is less than or equal to the stored document's version number, a version conflict will occur and the index operation will fail. For example:
PUT my-index-000001/_doc/1?version=2&version_type=external
{
"user": {
"id": "elkbee"
}
}
In this example, the operation will succeed since the supplied version of 2 is higher than the current document version of 1.
If the document was already updated and its version was set to 2 or higher, the indexing command will fail and result in a conflict (409 HTTP status code).
A nice side effect is that there is no need to maintain strict ordering of async indexing operations run as a result of changes to a source database, as long as version numbers from the source database are used.
Even the simple case of updating the Elasticsearch index using data from a database is simplified if external versioning is used, as only the latest version will be used if the index operations arrive out of order.
The name of the data stream or index to target.
If the target doesn't exist and matches the name or wildcard (*) pattern of an index template with a data_stream definition, this request creates the data stream.
If the target doesn't exist and doesn't match a data stream template, this request creates the index.
You can check for existing targets with the resolve index API.
A unique identifier for the document.
To automatically generate a document ID, use the POST /<target>/_doc/ request format and omit this parameter.
Only perform the operation if the document has this primary term.
Only perform the operation if the document has this sequence number.
True or false if to include the document source in the error message in case of parsing errors.
Set to create to only index the document if it does not already exist (put if absent).
If a document with the specified _id already exists, the indexing operation will fail.
The behavior is the same as using the <index>/_create endpoint.
If a document ID is specified, this paramater defaults to index.
Otherwise, it defaults to create.
If the request targets a data stream, an op_type of create is required.
Values are index or create.
The ID of the pipeline to use to preprocess incoming documents.
If the index has a default ingest pipeline specified, then setting the value to _none disables the default ingest pipeline for this request.
If a final pipeline is configured it will always run, regardless of the value of this parameter.
If true, Elasticsearch refreshes the affected shards to make this operation visible to search.
If wait_for, it waits for a refresh to make this operation visible to search.
If false, it does nothing with refreshes.
Values are true, false, or wait_for.
A custom value that is used to route operations to a specific shard.
The period the request waits for the following operations: automatic index creation, dynamic mapping updates, waiting for active shards.
This parameter is useful for situations where the primary shard assigned to perform the operation might not be available when the operation runs. Some reasons for this might be that the primary shard is currently recovering from a gateway or undergoing relocation. By default, the operation will wait on the primary shard to become available for at least 1 minute before failing and responding with an error. The actual wait time could be longer, particularly when multiple waits occur.
An explicit version number for concurrency control. It must be a non-negative long number.
The version type.
Values are internal, external, external_gte, or force.
The number of shard copies that must be active before proceeding with the operation.
You can set it to all or any positive integer up to the total number of shards in the index (number_of_replicas+1).
The default value of 1 means it waits for each primary shard to be active.
If true, the destination must be an index alias.

}Remove a JSON document from the specified index.
NOTE: You cannot send deletion requests directly to a data stream. To delete a document in a data stream, you must target the backing index containing the document.
Optimistic concurrency control
Delete operations can be made conditional and only be performed if the last modification to the document was assigned the sequence number and primary term specified by the if_seq_no and if_primary_term parameters.
If a mismatch is detected, the operation will result in a VersionConflictException and a status code of 409.
Versioning
Each document indexed is versioned.
When deleting a document, the version can be specified to make sure the relevant document you are trying to delete is actually being deleted and it has not changed in the meantime.
Every write operation run on a document, deletes included, causes its version to be incremented.
The version number of a deleted document remains available for a short time after deletion to allow for control of concurrent operations.
The length of time for which a deleted document's version remains available is determined by the index.gc_deletes index setting.
Routing
If routing is used during indexing, the routing value also needs to be specified to delete a document.
If the _routing mapping is set to required and no routing value is specified, the delete API throws a RoutingMissingException and rejects the request.
For example:
DELETE /my-index-000001/_doc/1?routing=shard-1
This request deletes the document with ID 1, but it is routed based on the user. The document is not deleted if the correct routing is not specified.
Distributed
The delete operation gets hashed into a specific shard ID. It then gets redirected into the primary shard within that ID group and replicated (if needed) to shard replicas within that ID group.
Only perform the operation if the document has this primary term.
Only perform the operation if the document has this sequence number.
If true, Elasticsearch refreshes the affected shards to make this operation visible to search.
If wait_for, it waits for a refresh to make this operation visible to search.
If false, it does nothing with refreshes.
Values are true, false, or wait_for.
A custom value used to route operations to a specific shard.
The period to wait for active shards.
This parameter is useful for situations where the primary shard assigned to perform the delete operation might not be available when the delete operation runs. Some reasons for this might be that the primary shard is currently recovering from a store or undergoing relocation. By default, the delete operation will wait on the primary shard to become available for up to 1 minute before failing and responding with an error.
An explicit version number for concurrency control. It must match the current version of the document for the request to succeed.
The version type.
Values are internal, external, external_gte, or force.
The minimum number of shard copies that must be active before proceeding with the operation.
You can set it to all or any positive integer up to the total number of shards in the index (number_of_replicas+1).
The default value of 1 means it waits for each primary shard to be active.
curl \
--request DELETE http://api.example.com/{index}/_doc/{id} \
--header "Authorization: $API_KEY"{
"_shards": {
"total": 2,
"failed": 0,
"successful": 2

"_id": "1",
"_version": 2,
"_primary_term": 1,
"_seq_no": 5,
"result": "deleted"
}Verify that a document exists.
For example, check to see if a document with the _id 0 exists:
HEAD my-index-000001/_doc/0
If the document exists, the API returns a status code of 200 - OK.
If the document doesn’t exist, the API returns 404 - Not Found.
Versioning support
You can use the version parameter to check the document only if its current version is equal to the specified one.
Internally, Elasticsearch has marked the old document as deleted and added an entirely new document. The old version of the document doesn't disappear immediately, although you won't be able to access it. Elasticsearch cleans up deleted documents in the background as you continue to index more data.
The node or shard the operation should be performed on. By default, the operation is randomized between the shard replicas.
If it is set to _local, the operation will prefer to be run on a local allocated shard when possible.
If it is set to a custom value, the value is used to guarantee that the same shards will be used for the same custom value.
This can help with "jumping values" when hitting different shards in different refresh states.
A sample value can be something like the web session ID or the user name.
If true, the request is real-time as opposed to near-real-time.
If true, the request refreshes the relevant shards before retrieving the document.
Setting it to true should be done after careful thought and verification that this does not cause a heavy load on the system (and slow down indexing).
A custom value used to route operations to a specific shard.
Indicates whether to return the _source field (true or false) or lists the fields to return.
A comma-separated list of source fields to exclude from the response.
You can also use this parameter to exclude fields from the subset specified in _source_includes query parameter.
If the _source parameter is false, this parameter is ignored.
A comma-separated list of source fields to include in the response.
If this parameter is specified, only these source fields are returned.
You can exclude fields from this subset using the _source_excludes query parameter.
If the _source parameter is false, this parameter is ignored.
A comma-separated list of stored fields to return as part of a hit.
If no fields are specified, no stored fields are included in the response.
If this field is specified, the _source parameter defaults to false.
Explicit version number for concurrency control. The specified version must match the current version of the document for the request to succeed.
The version type.
Values are internal, external, external_gte, or force.

});
console.log(response);
resp = client.exists(
index="my-index-000001",

)
print(resp)
response = client.exists(

Deletes documents that match the specified query.
If the Elasticsearch security features are enabled, you must have the following index privileges for the target data stream, index, or alias:
readdelete or writeYou can specify the query criteria in the request URI or the request body using the same syntax as the search API. When you submit a delete by query request, Elasticsearch gets a snapshot of the data stream or index when it begins processing the request and deletes matching documents using internal versioning. If a document changes between the time that the snapshot is taken and the delete operation is processed, it results in a version conflict and the delete operation fails.
NOTE: Documents with a version equal to 0 cannot be deleted using delete by query because internal versioning does not support 0 as a valid version number.
While processing a delete by query request, Elasticsearch performs multiple search requests sequentially to find all of the matching documents to delete. A bulk delete request is performed for each batch of matching documents. If a search or bulk request is rejected, the requests are retried up to 10 times, with exponential back off. If the maximum retry limit is reached, processing halts and all failed requests are returned in the response. Any delete requests that completed successfully still stick, they are not rolled back.
You can opt to count version conflicts instead of halting and returning by setting conflicts to proceed.
Note that if you opt to count version conflicts the operation could attempt to delete more documents from the source than max_docs until it has successfully deleted max_docs documents, or it has gone through every document in the source query.
Throttling delete requests
To control the rate at which delete by query issues batches of delete operations, you can set requests_per_second to any positive decimal number.
This pads each batch with a wait time to throttle the rate.
Set requests_per_second to -1 to disable throttling.
Throttling uses a wait time between batches so that the internal scroll requests can be given a timeout that takes the request padding into account.
The padding time is the difference between the batch size divided by the requests_per_second and the time spent writing.
By default the batch size is 1000, so if requests_per_second is set to 500:
target_time = 1000 / 500 per second = 2 seconds
wait_time = target_time - write_time = 2 seconds - .5 seconds = 1.5 seconds
Since the batch is issued as a single _bulk request, large batch sizes cause Elasticsearch to create many requests and wait before starting the next set.
This is "bursty" instead of "smooth".
Slicing
Delete by query supports sliced scroll to parallelize the delete process. This can improve efficiency and provide a convenient way to break the request down into smaller parts.
Setting slices to auto lets Elasticsearch choose the number of slices to use.
This setting will use one slice per shard, up to a certain limit.
If there are multiple source data streams or indices, it will choose the number of slices based on the index or backing index with the smallest number of shards.
Adding slices to the delete by query operation creates sub-requests which means it has some quirks:
slices will rethrottle the unfinished sub-request proportionally.slices will cancel each sub-request.slices each sub-request won't get a perfectly even portion of the documents. All documents will be addressed, but some slices may be larger than others. Expect larger slices to have a more even distribution.requests_per_second and max_docs on a request with slices are distributed proportionally to each sub-request. Combine that with the earlier point about distribution being uneven and you should conclude that using max_docs with slices might not result in exactly max_docs documents being deleted.If you're slicing manually or otherwise tuning automatic slicing, keep in mind that:
slices hurts performance. Setting slices higher than the number of shards generally does not improve efficiency and adds overhead.Whether query or delete performance dominates the runtime depends on the documents being reindexed and cluster resources.
Cancel a delete by query operation
Any delete by query can be canceled using the task cancel API. For example:
POST _tasks/r1A2WoRbTwKZ516z6NEs5A:36619/_cancel
The task ID can be found by using the get tasks API.
Cancellation should happen quickly but might take a few seconds. The get task status API will continue to list the delete by query task until this task checks that it has been cancelled and terminates itself.
A comma-separated list of data streams, indices, and aliases to search.
It supports wildcards (*).
To search all data streams or indices, omit this parameter or use * or _all.
If false, the request returns an error if any wildcard expression, index alias, or _all value targets only missing or closed indices.
This behavior applies even if the request targets other open indices.
For example, a request targeting foo*,bar* returns an error if an index starts with foo but no index starts with bar.
Analyzer to use for the query string.
This parameter can be used only when the q query string parameter is specified.
If true, wildcard and prefix queries are analyzed.
This parameter can be used only when the q query string parameter is specified.
What to do if delete by query hits version conflicts: abort or proceed.
Values are abort or proceed.
The default operator for query string query: AND or OR.
This parameter can be used only when the q query string parameter is specified.
Values are and, AND, or, or OR.
The field to use as default where no field prefix is given in the query string.
This parameter can be used only when the q query string parameter is specified.
The type of index that wildcard patterns can match.
If the request can target data streams, this argument determines whether wildcard expressions match hidden data streams.
It supports comma-separated values, such as open,hidden.
Skips the specified number of documents.
If true, format-based query failures (such as providing text to a numeric field) in the query string will be ignored.
This parameter can be used only when the q query string parameter is specified.
The maximum number of documents to process.
Defaults to all documents.
When set to a value less then or equal to scroll_size, a scroll will not be used to retrieve the results for the operation.
The node or shard the operation should be performed on. It is random by default.
If true, Elasticsearch refreshes all shards involved in the delete by query after the request completes.
This is different than the delete API's refresh parameter, which causes just the shard that received the delete request to be refreshed.
Unlike the delete API, it does not support wait_for.
If true, the request cache is used for this request.
Defaults to the index-level setting.
The throttle for this request in sub-requests per second.
A custom value used to route operations to a specific shard.
A query in the Lucene query string syntax.
The period to retain the search context for scrolling.
The size of the scroll request that powers the operation.
The explicit timeout for each search request. It defaults to no timeout.
The type of the search operation.
Available options include query_then_fetch and dfs_query_then_fetch.
Values are query_then_fetch or dfs_query_then_fetch.
The number of slices this task should be divided into.
A comma-separated list of <field>:<direction> pairs.
The specific tag of the request for logging and statistical purposes.
The maximum number of documents to collect for each shard. If a query reaches this limit, Elasticsearch terminates the query early. Elasticsearch collects documents before sorting.
Use with caution. Elasticsearch applies this parameter to each shard handling the request. When possible, let Elasticsearch perform early termination automatically. Avoid specifying this parameter for requests that target data streams with backing indices across multiple data tiers.
The period each deletion request waits for active shards.
If true, returns the document version as part of a hit.
The number of shard copies that must be active before proceeding with the operation.
Set to all or any positive integer up to the total number of shards in the index (number_of_replicas+1).
The timeout value controls how long each write request waits for unavailable shards to become available.
If true, the request blocks until the operation is complete.
If false, Elasticsearch performs some preflight checks, launches the request, and returns a task you can use to cancel or get the status of the task. Elasticsearch creates a record of this task as a document at .tasks/task/${taskId}. When you are done with a task, you should delete the task document so Elasticsearch can reclaim the space.

--header "Authorization: $API_KEY"Add a JSON document to the specified data stream or index and make it searchable. If the target is an index and the document already exists, the request updates the document and increments its version.
NOTE: You cannot use this API to send update requests for existing documents in a data stream.
If the Elasticsearch security features are enabled, you must have the following index privileges for the target data stream, index, or index alias:
PUT /<target>/_doc/<_id> request format, you must have the create, index, or write index privilege.POST /<target>/_doc/ request format, you must have the create_doc, create, index, or write index privilege.auto_configure, create_index, or manage index privilege.Automatic data stream creation requires a matching index template with data stream enabled.
NOTE: Replica shards might not all be started when an indexing operation returns successfully.
By default, only the primary is required. Set wait_for_active_shards to change this default behavior.
Automatically create data streams and indices
If the request's target doesn't exist and matches an index template with a data_stream definition, the index operation automatically creates the data stream.
If the target doesn't exist and doesn't match a data stream template, the operation automatically creates the index and applies any matching index templates.
NOTE: Elasticsearch includes several built-in index templates. To avoid naming collisions with these templates, refer to index pattern documentation.
If no mapping exists, the index operation creates a dynamic mapping. By default, new fields and objects are automatically added to the mapping if needed.
Automatic index creation is controlled by the action.auto_create_index setting.
If it is true, any index can be created automatically.
You can modify this setting to explicitly allow or block automatic creation of indices that match specified patterns or set it to false to turn off automatic index creation entirely.
Specify a comma-separated list of patterns you want to allow or prefix each pattern with + or - to indicate whether it should be allowed or blocked.
When a list is specified, the default behaviour is to disallow.
NOTE: The action.auto_create_index setting affects the automatic creation of indices only.
It does not affect the creation of data streams.
Optimistic concurrency control
Index operations can be made conditional and only be performed if the last modification to the document was assigned the sequence number and primary term specified by the if_seq_no and if_primary_term parameters.
If a mismatch is detected, the operation will result in a VersionConflictException and a status code of 409.
Routing
By default, shard placement — or routing — is controlled by using a hash of the document's ID value.
For more explicit control, the value fed into the hash function used by the router can be directly specified on a per-operation basis using the routing parameter.
When setting up explicit mapping, you can also use the _routing field to direct the index operation to extract the routing value from the document itself.
This does come at the (very minimal) cost of an additional document parsing pass.
If the _routing mapping is defined and set to be required, the index operation will fail if no routing value is provided or extracted.
NOTE: Data streams do not support custom routing unless they were created with the allow_custom_routing setting enabled in the template.
Distributed
The index operation is directed to the primary shard based on its route and performed on the actual node containing this shard. After the primary shard completes the operation, if needed, the update is distributed to applicable replicas.
Active shards
To improve the resiliency of writes to the system, indexing operations can be configured to wait for a certain number of active shard copies before proceeding with the operation.
If the requisite number of active shard copies are not available, then the write operation must wait and retry, until either the requisite shard copies have started or a timeout occurs.
By default, write operations only wait for the primary shards to be active before proceeding (that is to say wait_for_active_shards is 1).
This default can be overridden in the index settings dynamically by setting index.write.wait_for_active_shards.
To alter this behavior per operation, use the wait_for_active_shards request parameter.
Valid values are all or any positive integer up to the total number of configured copies per shard in the index (which is number_of_replicas+1).
Specifying a negative value or a number greater than the number of shard copies will throw an error.
For example, suppose you have a cluster of three nodes, A, B, and C and you create an index index with the number of replicas set to 3 (resulting in 4 shard copies, one more copy than there are nodes).
If you attempt an indexing operation, by default the operation will only ensure the primary copy of each shard is available before proceeding.
This means that even if B and C went down and A hosted the primary shard copies, the indexing operation would still proceed with only one copy of the data.
If wait_for_active_shards is set on the request to 3 (and all three nodes are up), the indexing operation will require 3 active shard copies before proceeding.
This requirement should be met because there are 3 active nodes in the cluster, each one holding a copy of the shard.
However, if you set wait_for_active_shards to all (or to 4, which is the same in this situation), the indexing operation will not proceed as you do not have all 4 copies of each shard active in the index.
The operation will timeout unless a new node is brought up in the cluster to host the fourth copy of the shard.
It is important to note that this setting greatly reduces the chances of the write operation not writing to the requisite number of shard copies, but it does not completely eliminate the possibility, because this check occurs before the write operation starts.
After the write operation is underway, it is still possible for replication to fail on any number of shard copies but still succeed on the primary.
The _shards section of the API response reveals the number of shard copies on which replication succeeded and failed.
No operation (noop) updates
When updating a document by using this API, a new version of the document is always created even if the document hasn't changed.
If this isn't acceptable use the _update API with detect_noop set to true.
The detect_noop option isn't available on this API because it doesn’t fetch the old source and isn't able to compare it against the new source.
There isn't a definitive rule for when noop updates aren't acceptable. It's a combination of lots of factors like how frequently your data source sends updates that are actually noops and how many queries per second Elasticsearch runs on the shard receiving the updates.
Versioning
Each indexed document is given a version number.
By default, internal versioning is used that starts at 1 and increments with each update, deletes included.
Optionally, the version number can be set to an external value (for example, if maintained in a database).
To enable this functionality, version_type should be set to external.
The value provided must be a numeric, long value greater than or equal to 0, and less than around 9.2e+18.
NOTE: Versioning is completely real time, and is not affected by the near real time aspects of search operations. If no version is provided, the operation runs without any version checks.
When using the external version type, the system checks to see if the version number passed to the index request is greater than the version of the currently stored document. If true, the document will be indexed and the new version number used. If the value provided is less than or equal to the stored document's version number, a version conflict will occur and the index operation will fail. For example:
PUT my-index-000001/_doc/1?version=2&version_type=external
{
"user": {
"id": "elkbee"
}
}
In this example, the operation will succeed since the supplied version of 2 is higher than the current document version of 1.
If the document was already updated and its version was set to 2 or higher, the indexing command will fail and result in a conflict (409 HTTP status code).
A nice side effect is that there is no need to maintain strict ordering of async indexing operations run as a result of changes to a source database, as long as version numbers from the source database are used.
Even the simple case of updating the Elasticsearch index using data from a database is simplified if external versioning is used, as only the latest version will be used if the index operations arrive out of order.
The name of the data stream or index to target.
If the target doesn't exist and matches the name or wildcard (*) pattern of an index template with a data_stream definition, this request creates the data stream.
If the target doesn't exist and doesn't match a data stream template, this request creates the index.
You can check for existing targets with the resolve index API.
Only perform the operation if the document has this primary term.
Only perform the operation if the document has this sequence number.
True or false if to include the document source in the error message in case of parsing errors.
Set to create to only index the document if it does not already exist (put if absent).
If a document with the specified _id already exists, the indexing operation will fail.
The behavior is the same as using the <index>/_create endpoint.
If a document ID is specified, this paramater defaults to index.
Otherwise, it defaults to create.
If the request targets a data stream, an op_type of create is required.
Values are index or create.
The ID of the pipeline to use to preprocess incoming documents.
If the index has a default ingest pipeline specified, then setting the value to _none disables the default ingest pipeline for this request.
If a final pipeline is configured it will always run, regardless of the value of this parameter.
If true, Elasticsearch refreshes the affected shards to make this operation visible to search.
If wait_for, it waits for a refresh to make this operation visible to search.
If false, it does nothing with refreshes.
Values are true, false, or wait_for.
A custom value that is used to route operations to a specific shard.
The period the request waits for the following operations: automatic index creation, dynamic mapping updates, waiting for active shards.
This parameter is useful for situations where the primary shard assigned to perform the operation might not be available when the operation runs. Some reasons for this might be that the primary shard is currently recovering from a gateway or undergoing relocation. By default, the operation will wait on the primary shard to become available for at least 1 minute before failing and responding with an error. The actual wait time could be longer, particularly when multiple waits occur.
An explicit version number for concurrency control. It must be a non-negative long number.
The version type.
Values are internal, external, external_gte, or force.
The number of shard copies that must be active before proceeding with the operation.
You can set it to all or any positive integer up to the total number of shards in the index (number_of_replicas+1).
The default value of 1 means it waits for each primary shard to be active.
If true, the destination must be an index alias.

}Get multiple JSON documents by ID from one or more indices. If you specify an index in the request URI, you only need to specify the document IDs in the request body. To ensure fast responses, this multi get (mget) API responds with partial results if one or more shards fail.
Filter source fields
By default, the _source field is returned for every document (if stored).
Use the _source and _source_include or source_exclude attributes to filter what fields are returned for a particular document.
You can include the _source, _source_includes, and _source_excludes query parameters in the request URI to specify the defaults to use when there are no per-document instructions.
Get stored fields
Use the stored_fields attribute to specify the set of stored fields you want to retrieve.
Any requested fields that are not stored are ignored.
You can include the stored_fields query parameter in the request URI to specify the defaults to use when there are no per-document instructions.
Name of the index to retrieve documents from when ids are specified, or when a document in the docs array does not specify an index.

}The Elasticsearch Query Language (ES|QL) provides a powerful way to filter, transform, and analyze data stored in Elasticsearch, and in the future in other runtimes.
Extract and summarize information about the documents and terms in an Elasticsearch data stream or index.
The easiest way to understand the behavior of this API is to use the Graph UI to explore connections.
An initial request to the _explore API contains a seed query that identifies the documents of interest and specifies the fields that define the vertices and connections you want to include in the graph.
Subsequent requests enable you to spider out from one more vertices of interest.

Values are metadata, read, read_only, or write.
If false, the request returns an error if any wildcard expression, index alias, or _all value targets only missing or closed indices.
This behavior applies even if the request targets other open indices.
For example, a request targeting foo*,bar* returns an error if an index starts with foo but no index starts with bar.
The type of index that wildcard patterns can match.
If the request can target data streams, this argument determines whether wildcard expressions match hidden data streams.
It supports comma-separated values, such as open,hidden.

If the master node is not available before the timeout expires, the request fails and returns an error.
It can also be set to -1 to indicate that the request should never timeout.
The period to wait for a response from all relevant nodes in the cluster after updating the cluster metadata.
If no response is received before the timeout expires, the cluster metadata update still applies but the response will indicate that it was not completely acknowledged.

}The analyze API performs analysis on a text string and returns the resulting tokens.
Generating excessive amount of tokens may cause a node to run out of memory.
The index.analyze.max_token_count setting enables you to limit the number of tokens that can be produced.
If more than this limit of tokens gets generated, an error occurs.
The _analyze endpoint without a specified index will always use 10000 as its limit.

}You can use the create index API to add a new index to an Elasticsearch cluster. When creating an index, you can specify the following:
Wait for active shards
By default, index creation will only return a response to the client when the primary copies of each shard have been started, or the request times out.
The index creation response will indicate what happened.
For example, acknowledged indicates whether the index was successfully created in the cluster, while shards_acknowledged indicates whether the requisite number of shard copies were started for each shard in the index before timing out.
Note that it is still possible for either acknowledged or shards_acknowledged to be false, but for the index creation to be successful.
These values simply indicate whether the operation completed before the timeout.
If acknowledged is false, the request timed out before the cluster state was updated with the newly created index, but it probably will be created sometime soon.
If shards_acknowledged is false, then the request timed out before the requisite number of shards were started (by default just the primaries), even if the cluster state was successfully updated to reflect the newly created index (that is to say, acknowledged is true).
You can change the default of only waiting for the primary shards to start through the index setting index.write.wait_for_active_shards.
Note that changing this setting will also affect the wait_for_active_shards value on all subsequent write operations.
Name of the index you wish to create.
Period to wait for a connection to the master node. If no response is received before the timeout expires, the request fails and returns an error.
Period to wait for a response. If no response is received before the timeout expires, the request fails and returns an error.

}Deleting an index deletes its documents, shards, and metadata. It does not delete related Kibana components, such as data views, visualizations, or dashboards.
You cannot delete the current write index of a data stream. To delete the index, you must roll over the data stream so a new write index is created. You can then use the delete index API to delete the previous write index.
Comma-separated list of indices to delete.
You cannot specify index aliases.
By default, this parameter does not support wildcards (*) or _all.
To use wildcards or _all, set the action.destructive_requires_name cluster setting to false.

If true, returns settings in flat format.
Period to wait for a connection to the master node. If no response is received before the timeout expires, the request fails and returns an error.
If true, returns all relevant default configurations for the index template.
curl \
--request GET http://api.example.com/_index_template/{name} \
--header "Authorization: $API_KEY"Index templates define settings, mappings, and aliases that can be applied automatically to new indices.
Elasticsearch applies templates to new indices based on an wildcard pattern that matches the index name. Index templates are applied during data stream or index creation. For data streams, these settings and mappings are applied when the stream's backing indices are created. Settings and mappings specified in a create index API request override any settings or mappings specified in an index template. Changes to index templates do not affect existing indices, including the existing backing indices of a data stream.
You can use C-style /* *\/ block comments in index templates.
You can include comments anywhere in the request body, except before the opening curly bracket.
Multiple matching templates
If multiple index templates match the name of a new index or data stream, the template with the highest priority is used.
Multiple templates with overlapping index patterns at the same priority are not allowed and an error will be thrown when attempting to create a template matching an existing index template at identical priorities.
Composing aliases, mappings, and settings
When multiple component templates are specified in the composed_of field for an index template, they are merged in the order specified, meaning that later component templates override earlier component templates.
Any mappings, settings, or aliases from the parent index template are merged in next.
Finally, any configuration on the index request itself is merged.
Mapping definitions are merged recursively, which means that later mapping components can introduce new field mappings and update the mapping configuration.
If a field mapping is already contained in an earlier component, its definition will be completely overwritten by the later one.
This recursive merging strategy applies not only to field mappings, but also root options like dynamic_templates and meta.
If an earlier component contains a dynamic_templates block, then by default new dynamic_templates entries are appended onto the end.
If an entry already exists with the same key, then it is overwritten by the new definition.
Index or template name
If true, this request cannot replace or update existing index templates.
Period to wait for a connection to the master node. If no response is received before the timeout expires, the request fails and returns an error.
User defined reason for creating/updating the index template
An ordered list of component template names. Component templates are merged in the order specified, meaning that the last component template specified has the highest precedence.
Priority to determine index template precedence when a new data stream or index is created. The index template with the highest priority is chosen. If no priority is specified the template is treated as though it is of priority 0 (lowest priority). This number is not automatically generated by Elasticsearch.
This setting overrides the value of the action.auto_create_index cluster setting.
If set to true in a template, then indices can be automatically created using that template even if auto-creation of indices is disabled via actions.auto_create_index.
If set to false, then indices or data streams matching the template must always be explicitly created, and may never be automatically created.
The configuration option ignore_missing_component_templates can be used when an index template references a component template that might not exist
Marks this index template as deprecated. When creating or updating a non-deprecated index template that uses deprecated components, Elasticsearch will emit a deprecation warning.

Add multi-fields to an existing field
Multi-fields let you index the same field in different ways. You can use this API to update the fields mapping parameter and enable multi-fields for an existing field. WARNING: If an index (or data stream) contains documents when you add a multi-field, those documents will not have values for the new multi-field. You can populate the new multi-field with the update by query API.
Change supported mapping parameters for an existing field
The documentation for each mapping parameter indicates whether you can update it for an existing field using this API.
For example, you can use the update mapping API to update the ignore_above parameter.
Change the mapping of an existing field
Except for supported mapping parameters, you can't change the mapping or field type of an existing field. Changing an existing field could invalidate data that's already indexed.
If you need to change the mapping of a field in a data stream's backing indices, refer to documentation about modifying data streams. If you need to change the mapping of a field in other indices, create a new index with the correct mapping and reindex your data into that index.
Rename a field
Renaming a field would invalidate data already indexed under the old field name. Instead, add an alias field to create an alternate field name.

You can change this default interval with the index.refresh_interval setting.
Refresh requests are synchronous and do not return a response until the refresh operation completes.
Refreshes are resource-intensive. To ensure good cluster performance, it's recommended to wait for Elasticsearch's periodic refresh rather than performing an explicit refresh when possible.

Avoid creating multiple endpoints for the same model unless required, as each endpoint consumes significant resources.
IMPORTANT: The inference APIs enable you to use certain services, such as built-in machine learning models (ELSER, E5), models uploaded through Eland, Cohere, OpenAI, Mistral, Azure OpenAI, Google AI Studio, Google Vertex AI, Anthropic, Watsonx.ai, or Hugging Face. For built-in models and models uploaded through Eland, the inference APIs offer an alternative way to use and manage trained models.
