Authentication

The API accepts 3 different authentication methods:

Api key auth (http_api_key)

Elasticsearch APIs support 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, use the /_security/api_key APIs.

Basic auth (http)

Basic auth tokens are constructed with the Basic keyword, followed by a space, followed by a base64-encoded string of your username:password (separated by a : colon).

Example: send a Authorization: Basic aGVsbG86aGVsbG8= HTTP header with your requests to authenticate with the API.

Bearer auth (http)

Elasticsearch APIs support the use of bearer tokens in the Authorization HTTP header to authenticate with the API. For examples, refer to Token-based authentication services









Delete an autoscaling policy Added in 7.11.0

Get the autoscaling capacity Added in 7.11.0

GET /_autoscaling/capacity

NOTE: This feature is designed for indirect use by Elasticsearch Service, Elastic Cloud Enterprise, and Elastic Cloud on Kubernetes. Direct use is not supported.

This API gets the current autoscaling capacity based on the configured autoscaling policy. It will return information to size the cluster appropriately to the current workload.

The required_capacity is calculated as the maximum of the required_capacity result of all individual deciders that are enabled for the policy.

The operator should verify that the current_nodes match the operator’s knowledge of the cluster to avoid making autoscaling decisions based on stale or incomplete information.

The response contains decider-specific information you can use to diagnose how and why autoscaling determined a certain capacity was required. This information is provided for diagnosis only. Do not use this information to make autoscaling decisions.

Query parameters

  • 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.

Explain the shard allocations Added in 5.0.0

GET /_cluster/allocation/explain

Get explanations for shard allocations in the cluster. For unassigned shards, it provides an explanation for why the shard is unassigned. For assigned shards, it provides an explanation for why the shard is remaining on its current node and has not moved or rebalanced to another node. This API can be very useful when attempting to diagnose why a shard is unassigned or why a shard continues to remain on its current node when you might expect otherwise.

Query parameters

application/json

Body

  • Specifies the node ID or the name of the node to only explain a shard that is currently located on the specified node.

  • index string
  • primary boolean

    If true, returns explanation for the primary shard for the given shard ID.

  • shard number

    Specifies the ID of the shard that you would like an explanation for.

Get the cluster health Added in 8.7.0

GET /_health_report/{feature}

Get a report with the health status of an Elasticsearch cluster. The report contains a list of indicators that compose Elasticsearch functionality.

Each indicator has a health status of: green, unknown, yellow or red. The indicator will provide an explanation and metadata describing the reason for its current health status.

The cluster’s status is controlled by the worst indicator status.

In the event that an indicator’s status is non-green, a list of impacts may be present in the indicator result which detail the functionalities that are negatively affected by the health issue. Each impact carries with it a severity level, an area of the system that is affected, and a simple description of the impact on the system.

Some health indicators can determine the root cause of a health problem and prescribe a set of steps that can be performed in order to improve the health of the system. The root cause and remediation steps are encapsulated in a diagnosis. A diagnosis contains a cause detailing a root cause analysis, an action containing a brief description of the steps to take to fix the problem, the list of affected resources (if applicable), and a detailed step-by-step troubleshooting guide to fix the diagnosed problem.

NOTE: The health indicators perform root cause analysis of non-green health statuses. This can be computationally expensive when called frequently. When setting up automated polling of the API for health status, set verbose to false to disable the more expensive analysis logic.

Path parameters

  • feature string | array[string] Required

    A feature of the cluster, as returned by the top-level health report API.

Query parameters

  • timeout string

    Explicit operation timeout.

  • verbose boolean

    Opt-in for more information about the health of the system.

  • size number

    Limit the number of affected resources the health report API returns.

Create a follower Added in 6.5.0

PUT /{index}/_ccr/follow

Create a cross-cluster replication follower index that follows a specific leader index. When the API returns, the follower index exists and cross-cluster replication starts replicating operations from the leader index to the follower index.

Path parameters

  • index string Required

    The name of the follower index.

Query parameters

  • Period to wait for a connection to the master node.

  • wait_for_active_shards number | string

    Specifies the number of shards to wait on being active before responding. This defaults to waiting on none of the shards to be active. A shard must be restored from the leader index before being active. Restoring a follower shard requires transferring all the remote Lucene segment files to the follower index.

application/json

Body Required

  • If the leader index is part of a data stream, the name to which the local data stream for the followed index should be renamed.

  • leader_index string Required
  • The maximum number of outstanding reads requests from the remote cluster.

  • The maximum number of outstanding write requests on the follower.

  • The maximum number of operations to pull per read from the remote cluster.

  • A duration. Units can be nanos, micros, ms (milliseconds), s (seconds), m (minutes), h (hours) and d (days). Also accepts "0" without a unit and "-1" to indicate an unspecified value.

  • The maximum number of operations that can be queued for writing. When this limit is reached, reads from the remote cluster will be deferred until the number of queued operations goes below the limit.

  • The maximum number of operations per bulk write request executed on the follower.

  • A duration. Units can be nanos, micros, ms (milliseconds), s (seconds), m (minutes), h (hours) and d (days). Also accepts "0" without a unit and "-1" to indicate an unspecified value.

  • remote_cluster string Required

    The remote cluster containing the leader index.

  • settings object

    Additional properties are allowed.

    Hide settings attributes Show settings attributes object
    • index object

      Additional properties are allowed.

    • mode string
    • Additional properties are allowed.

      Hide soft_deletes attributes Show soft_deletes attributes object
      • enabled boolean

        Indicates whether soft deletes are enabled on the index.

      • Additional properties are allowed.

        Hide retention_lease attribute Show retention_lease attribute object
        • period string Required

          A duration. Units can be nanos, micros, ms (milliseconds), s (seconds), m (minutes), h (hours) and d (days). Also accepts "0" without a unit and "-1" to indicate an unspecified value.

    • sort object

      Additional properties are allowed.

      Hide sort attributes Show sort attributes object
    • Values are true, false, or checksum.

    • codec string
    • routing_partition_size number | string

      Some APIs will return values such as numbers also as a string (notably epoch timestamps). This behavior is used to capture this behavior while keeping the semantics of the field type.

      Depending on the target language, code generators can keep the union or remove it and leniently parse strings to the target type.

    • merge object

      Additional properties are allowed.

      Hide merge attribute Show merge attribute object
    • A duration. Units can be nanos, micros, ms (milliseconds), s (seconds), m (minutes), h (hours) and d (days). Also accepts "0" without a unit and "-1" to indicate an unspecified value.

      Hide lifecycle attributes Show lifecycle attributes object
      • name string
      • indexing_complete boolean | string

        Some APIs will return values such as numbers also as a string (notably epoch timestamps). This behavior is used to capture this behavior while keeping the semantics of the field type.

        Depending on the target language, code generators can keep the union or remove it and leniently parse strings to the target type.

      • If specified, this is the timestamp used to calculate the index age for its phase transitions. Use this setting if you create a new index that contains old data and want to use the original creation date to calculate the index age. Specified as a Unix epoch value in milliseconds.

      • Set to true to parse the origination date from the index name. This origination date is used to calculate the index age for its phase transitions. The index name must match the pattern .*-{date_format}-\d+, where the date_format is yyyy.MM.dd and the trailing digits are optional. An index that was rolled over would normally match the full format, for example logs-2016.10.31-000002). If the index name doesn’t match the pattern, index creation fails.

      • step object

        Additional properties are allowed.

        Hide step attribute Show step attribute object
        • A duration. Units can be nanos, micros, ms (milliseconds), s (seconds), m (minutes), h (hours) and d (days). Also accepts "0" without a unit and "-1" to indicate an unspecified value.

      • The index alias to update when the index rolls over. Specify when using a policy that contains a rollover action. When the index rolls over, the alias is updated to reflect that the index is no longer the write index. For more information about rolling indices, see Rollover.

      • prefer_ilm boolean | string

        Preference for the system that manages a data stream backing index (preferring ILM when both ILM and DLM are applicable for an index).

    • creation_date number | string

      Some APIs will return values such as numbers also as a string (notably epoch timestamps). This behavior is used to capture this behavior while keeping the semantics of the field type.

      Depending on the target language, code generators can keep the union or remove it and leniently parse strings to the target type.

    • creation_date_string string | number

      A date and time, either as a string whose format can depend on the context (defaulting to ISO 8601), or a number of milliseconds since the Epoch. Elasticsearch accepts both as input, but will generally output a string representation.

    • uuid string

      • coerce boolean
      • Additional properties are allowed.

        Hide total_fields attributes Show total_fields attributes object
        • limit number | string

          The maximum number of fields in an index. Field and object mappings, as well as field aliases count towards this limit. The limit is in place to prevent mappings and searches from becoming too large. Higher values can lead to performance degradations and memory issues, especially in clusters with a high load or few resources.

        • ignore_dynamic_beyond_limit boolean | string

          This setting determines what happens when a dynamically mapped field would exceed the total fields limit. When set to false (the default), the index request of the document that tries to add a dynamic field to the mapping will fail with the message Limit of total fields [X] has been exceeded. When set to true, the index request will not fail. Instead, fields that would exceed the limit are not added to the mapping, similar to dynamic: false. The fields that were not added to the mapping will be added to the _ignored field.

      • depth object

        Additional properties are allowed.

        Hide depth attribute Show depth attribute object
        • limit number

          The maximum depth for a field, which is measured as the number of inner objects. For instance, if all fields are defined at the root object level, then the depth is 1. If there is one object mapping, then the depth is 2, etc.

      • Additional properties are allowed.

        Hide nested_fields attribute Show nested_fields attribute object
        • limit number

          The maximum number of distinct nested mappings in an index. The nested type should only be used in special cases, when arrays of objects need to be queried independently of each other. To safeguard against poorly designed mappings, this setting limits the number of unique nested types per index.

      • Additional properties are allowed.

        Hide nested_objects attribute Show nested_objects attribute object
        • limit number

          The maximum number of nested JSON objects that a single document can contain across all nested types. This limit helps to prevent out of memory errors when a document contains too many nested objects.

      • Additional properties are allowed.

        Hide field_name_length attribute Show field_name_length attribute object
        • limit number

          Setting for the maximum length of a field name. This setting isn’t really something that addresses mappings explosion but might still be useful if you want to limit the field length. It usually shouldn’t be necessary to set this setting. The default is okay unless a user starts to add a huge number of fields with really long names. Default is Long.MAX_VALUE (no limit).

      • Additional properties are allowed.

        Hide dimension_fields attribute Show dimension_fields attribute object
        • limit number

          [preview] This functionality is in technical preview and may be changed or removed in a future release. Elastic will work to fix any issues, but features in technical preview are not subject to the support SLA of official GA features.

        Hide memory attribute Show memory attribute object
        • limit number

          Number of outstanding bytes that may be consumed by indexing requests. When this limit is reached or exceeded, the node will reject new coordinating and primary operations. When replica operations consume 1.5x this limit, the node will reject new replica operations. Defaults to 10% of the heap.

    • store object

      Additional properties are allowed.

      Hide store attributes Show store attributes object
      • type string Required

      • allow_mmap boolean

        You can restrict the use of the mmapfs and the related hybridfs store type via the setting node.store.allow_mmap. This is a boolean setting indicating whether or not memory-mapping is allowed. The default is to allow it. This setting is useful, for example, if you are in an environment where you can not control the ability to create a lot of memory maps so you need disable the ability to use memory-mapping.

Downsample an index Technical preview

POST /{index}/_downsample/{target_index}

Aggregate a time series (TSDS) index and store pre-computed statistical summaries (min, max, sum, value_count and avg) for each metric field grouped by a configured time interval. For example, a TSDS index that contains metrics sampled every 10 seconds can be downsampled to an hourly index. All documents within an hour interval are summarized and stored as a single document in the downsample index.

NOTE: Only indices in a time series data stream are supported. Neither field nor document level security can be defined on the source index. The source index must be read only (index.blocks.write: true).

Path parameters

  • index string Required

    Name of the time series index to downsample.

  • target_index string Required

    Name of the index to create.

Get term vector information

POST /{index}/_termvectors/{id}

Get information and statistics about terms in the fields of a particular document.

You can retrieve term vectors for documents stored in the index or for artificial documents passed in the body of the request. You can specify the fields you are interested in through the fields parameter or by adding the fields to the request body. For example:

GET /my-index-000001/_termvectors/1?fields=message

Fields can be specified using wildcards, similar to the multi match query.

Term vectors are real-time by default, not near real-time. This can be changed by setting realtime parameter to false.

You can request three types of values: term information, term statistics, and field statistics. By default, all term information and field statistics are returned for all fields but term statistics are excluded.

Term information

  • term frequency in the field (always returned)
  • term positions (positions: true)
  • start and end offsets (offsets: true)
  • term payloads (payloads: true), as base64 encoded bytes

If the requested information wasn't stored in the index, it will be computed on the fly if possible. Additionally, term vectors could be computed for documents not even existing in the index, but instead provided by the user.


Start and end offsets assume UTF-16 encoding is being used. If you want to use these offsets in order to get the original text that produced this token, you should make sure that the string you are taking a sub-string of is also encoded using UTF-16.

Behaviour

The term and field statistics are not accurate. Deleted documents are not taken into account. The information is only retrieved for the shard the requested document resides in. The term and field statistics are therefore only useful as relative measures whereas the absolute numbers have no meaning in this context. By default, when requesting term vectors of artificial documents, a shard to get the statistics from is randomly selected. Use routing only to hit a particular shard.

Path parameters

  • index string Required

    The name of the index that contains the document.

  • id string Required

    A unique identifier for the document.

Query parameters

  • fields string | array[string]

    A comma-separated list or wildcard expressions of fields to include in the statistics. It is used as the default list unless a specific field list is provided in the completion_fields or fielddata_fields parameters.

  • If true, the response includes:

    • The document count (how many documents contain this field).
    • The sum of document frequencies (the sum of document frequencies for all terms in this field).
    • The sum of total term frequencies (the sum of total term frequencies of each term in this field).
  • offsets boolean

    If true, the response includes term offsets.

  • payloads boolean

    If true, the response includes term payloads.

  • positions boolean

    If true, the response includes term positions.

  • The node or shard the operation should be performed on. It is random by default.

  • realtime boolean

    If true, the request is real-time as opposed to near-real-time.

  • routing string

    A custom value that is used to route operations to a specific shard.

  • If true, the response includes:

    • The total term frequency (how often a term occurs in all documents).
    • The document frequency (the number of documents containing the current term).

    By default these values are not returned since term statistics can have a serious performance impact.

  • version number

    If true, returns the document version as part of a hit.

  • The version type.

    Values are internal, external, external_gte, or force.

application/json

Body

  • doc object

    An artificial document (a document not present in the index) for which you want to retrieve term vectors.

    Additional properties are allowed.

  • filter object

    Additional properties are allowed.

    Hide filter attributes Show filter attributes object
    • Ignore words which occur in more than this many docs. Defaults to unbounded.

    • The maximum number of terms that must be returned per field.

    • Ignore words with more than this frequency in the source doc. It defaults to unbounded.

    • The maximum word length above which words will be ignored. Defaults to unbounded.

    • Ignore terms which do not occur in at least this many docs.

    • Ignore words with less than this frequency in the source doc.

    • The minimum word length below which words will be ignored.

  • Override the default per-field analyzer. This is useful in order to generate term vectors in any fashion, especially when using artificial documents. When providing an analyzer for a field that already stores term vectors, the term vectors will be regenerated.

  "term_statistics" : true,
  "field_statistics" : true
}
Run `GET /my-index-000001/_termvectors/1` to set per-field analyzers. A different analyzer than the one at the field may be provided by using the `per_field_analyzer` parameter.
{
  "doc" : {
    "fullname" : "John Doe",
    "text" : "test test test"
  },
  "fields": ["fullname"],
  "per_field_analyzer" : {
    "fullname": "keyword"
  }
}
Run `GET /imdb/_termvectors` to filter the terms returned based on their tf-idf scores. It returns the three most "interesting" keywords from the artificial document having the given "plot" field value. Notice that the keyword "Tony" or any stop words are not part of the response, as their tf-idf must be too low.

  "doc": {
    "plot": "When wealthy industrialist Tony Stark is forced to build an armored suit after a life-threatening incident, he ultimately decides to use its technology to fight against evil."

}
Run `GET /my-index-000001/_termvectors/1`. Term vectors which are not explicitly stored in the index are automatically computed on the fly. This request returns all information and statistics for the fields in document 1, even though the terms haven't been explicitly stored in the index. Note that for the field text, the terms are not regenerated.

}
Run `GET /my-index-000001/_termvectors`. Term vectors can be generated for artificial documents, that is for documents not present in the index. If dynamic mapping is turned on (default), the document fields not in the original mapping will be dynamically created.

Get the async EQL status Added in 7.9.0

GET /_eql/search/status/{id}

Get the current status for an async EQL search or a stored synchronous EQL search without returning results.

Path parameters

  • id string Required

    Identifier for the search.

Responses

  • 200 application/json
    Hide response attributes Show response attributes object
    • id string Required
    • is_partial boolean Required

      If true, the search request is still executing. If false, the search is completed.

    • is_running boolean Required

      If true, the response does not contain complete search results. This could be because either the search is still running (is_running status is false), or because it is already completed (is_running status is true) and results are partial due to failures or timeouts.

    • Time unit for milliseconds

    • Time unit for milliseconds

    • For a completed search shows the http status code of the completed search.
