Compact and aligned text (CAT)

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 field data cache information

GET /_cat/fielddata

Get the amount of heap memory currently used by the field data cache on every data node in the cluster.

IMPORTANT: cat APIs are only intended for human consumption using the command line or Kibana console. They are not intended for use by applications. For application consumption, use the nodes stats API.

Query parameters

  • bytes string

    The unit used to display byte values.

    Values are b, kb, mb, gb, tb, or pb.

  • fields string | array[string]

    Comma-separated list of fields used to limit returned information.

  • h string | array[string]

    List of columns to appear in the response. Supports simple wildcards.

  • s string | array[string]

    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.

Explain the shard allocations Added in 5.0.0

POST /_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.

Simulate an index template

POST /_index_template/_simulate

Get the index configuration that would be applied by a particular index template.

Query parameters

  • create boolean

    If true, the template passed in the body is only used if no existing templates match the same index patterns. If false, the simulation uses the template with the highest priority. Note that the template is not permanently added or updated in either case; it is only used for the simulation.

  • cause string

    User defined reason for dry-run creating the new template for simulation purposes

  • 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.

application/json

Body

  • 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.

  • index_patterns string | array[string]
  • composed_of array[string]

    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.

  • template object
    Hide template attributes Show template attributes object
    • aliases object

      Aliases to add. If the index template includes a data_stream object, these are data stream aliases. Otherwise, these are index aliases. Data stream aliases ignore the index_routing, routing, and search_routing options.

          • 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.

            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.

        • 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.

        • 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).

            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.

          Hide store attributes Show store attributes object
          • type string Required

            Any of:

            Values are fs, niofs, mmapfs, or hybridfs.

          • 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.

      • 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.

        Hide cache attribute Show cache attribute object
    • Configure custom similarity settings to customize how search results are scored.

    • mapping object
      Hide mapping attributes Show mapping attributes object
      • coerce boolean
      • 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
        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.

      • 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.

      • 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.

      • 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).

      • 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.

      • memory object Required
        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.

Run a search

POST /{index}/_search

Get search hits that match the query defined in the request. You can provide search queries using the q query string parameter or the request body. If both are specified, only the query parameter is used.

If the Elasticsearch security features are enabled, you must have the read index privilege for the target data stream, index, or alias. For cross-cluster search, refer to the documentation about configuring CCS privileges. To search a point in time (PIT) for an alias, you must have the read index privilege for the alias's data streams or indices.

Search slicing

When paging through a large number of documents, it can be helpful to split the search into multiple slices to consume them independently with the slice and pit properties. By default the splitting is done first on the shards, then locally on each shard. The local splitting partitions the shard into contiguous ranges based on Lucene document IDs.

For instance if the number of shards is equal to 2 and you request 4 slices, the slices 0 and 2 are assigned to the first shard and the slices 1 and 3 are assigned to the second shard.

IMPORTANT: The same point-in-time ID should be used for all slices. If different PIT IDs are used, slices can overlap and miss documents. This situation can occur because the splitting criterion is based on Lucene document IDs, which are not stable across changes to the index.

External documentation

Path parameters

  • index string | array[string] Required

    A comma-separated list of data streams, indices, and aliases to search. It supports wildcards (*). To search all data streams and indices, omit this parameter or use * or _all.

Query parameters

  • 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.

  • If true and there are shard request timeouts or shard failures, the request returns partial results. If false, it returns an error with no partial results.

    To override the default behavior, you can set the search.default_allow_partial_results cluster setting to false.

  • analyzer string

    The 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.

  • The number of shard results that should be reduced at once on the coordinating node. If the potential number of shards in the request can be large, this value should be used as a protection mechanism to reduce the memory overhead per search request.

  • If true, network round-trips between the coordinating node and the remote clusters are minimized when running cross-cluster search (CCS) requests.

  • The default operator for the 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.

  • df string

    The field to use as a default when no field prefix is given in the query string. This parameter can be used only when the q query string parameter is specified.

  • docvalue_fields string | array[string]

    A comma-separated list of fields to return as the docvalue representation of a field for each hit.

  • expand_wildcards string | array[string]

    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.

  • explain boolean

    If true, the request returns detailed information about score computation as part of a hit.

  • ignore_throttled boolean Deprecated

    If true, concrete, expanded or aliased indices will be ignored when frozen.

  • If false, the request returns an error if it targets a missing or closed index.

  • If true, the response includes the score contribution from any named queries.

    This functionality reruns each named query on every hit in a search response. Typically, this adds a small overhead to a request. However, using computationally expensive named queries on a large number of hits may add significant overhead.

  • lenient boolean

    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 number of concurrent shard requests per node that the search runs concurrently. This value should be used to limit the impact of the search on the cluster in order to limit the number of concurrent shard requests.

  • The minimum version of the node that can handle the request Any handling node with a lower version will fail the request.

  • The nodes and shards used for the search. By default, Elasticsearch selects from eligible nodes and shards using adaptive replica selection, accounting for allocation awareness. Valid values are:

    • _only_local to run the search only on shards on the local node;
    • _local to, if possible, run the search on shards on the local node, or if not, select shards using the default method;
    • _only_nodes:<node-id>,<node-id> to run the search on only the specified nodes IDs, where, if suitable shards exist on more than one selected node, use shards on those nodes using the default method, or if none of the specified nodes are available, select shards from any available node using the default method;
    • _prefer_nodes:<node-id>,<node-id> to if possible, run the search on the specified nodes IDs, or if not, select shards using the default method;
    • _shards:<shard>,<shard> to run the search only on the specified shards;
    • <custom-string> (any string that does not start with _) to route searches with the same <custom-string> to the same shards in the same order.
  • A threshold that enforces a pre-filter roundtrip to prefilter search shards based on query rewriting if the number of shards the search request expands to exceeds the threshold. This filter roundtrip can limit the number of shards significantly if for instance a shard can not match any documents based on its rewrite method (if date filters are mandatory to match but the shard bounds and the query are disjoint). When unspecified, the pre-filter phase is executed if any of these conditions is met:

    • The request targets more than 128 shards.
    • The request targets one or more read-only index.
    • The primary sort of the query targets an indexed field.
  • If true, the caching of search results is enabled for requests where size is 0. It defaults to index level settings.

  • routing string

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

  • scroll string

    The period to retain the search context for scrolling. By default, this value cannot exceed 1d (24 hours). You can change this limit by using the search.max_keep_alive cluster-level setting.

  • Indicates how distributed term frequencies are calculated for relevance scoring.

    Values are query_then_fetch or dfs_query_then_fetch.

  • stats array[string]

    Specific tag of the request for logging and statistical purposes.

  • stored_fields string | array[string]

    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. You can pass _source: true to return both source fields and stored fields in the search response.

  • The field to use for suggestions.

  • The suggest mode. This parameter can be used only when the suggest_field and suggest_text query string parameters are specified.

    Values are missing, popular, or always.

  • The number of suggestions to return. This parameter can be used only when the suggest_field and suggest_text query string parameters are specified.

  • The source text for which the suggestions should be returned. This parameter can be used only when the suggest_field and suggest_text query string parameters are specified.

  • 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.

    IMPORTANT: 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. If set to 0 (default), the query does not terminate early.

  • timeout string

    The period of time to wait for a response from each shard. If no response is received before the timeout expires, the request fails and returns an error. It defaults to no timeout.

  • track_total_hits boolean | number

    The number of hits matching the query to count accurately. If true, the exact number of hits is returned at the cost of some performance. If false, the response does not include the total number of hits matching the query.

  • If true, the request calculates and returns document scores, even if the scores are not used for sorting.

  • typed_keys boolean

    If true, aggregation and suggester names are be prefixed by their respective types in the response.

  • Indicates whether hits.total should be rendered as an integer or an object in the rest search response.

  • version boolean

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

  • _source boolean | string | array[string]

    The source fields that are returned for matching documents. These fields are returned in the hits._source property of the search response. Valid values are:

    • true to return the entire document source.
    • false to not return the document source.
    • <string> to return the source fields that are specified as a comma-separated list that supports wildcard (*) patterns.
  • _source_excludes string | array[string]

    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.

  • _source_includes string | array[string]

    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.

  • If true, the request returns the sequence number and primary term of the last modification of each hit.

  • q string

    A query in the Lucene query string syntax. Query parameter searches do not support the full Elasticsearch Query DSL but are handy for testing.

    IMPORTANT: This parameter overrides the query parameter in the request body. If both parameters are specified, documents matching the query request body parameter are not returned.

  • size number

    The number of hits to return. By default, you cannot page through more than 10,000 hits using the from and size parameters. To page through more hits, use the search_after parameter.

  • from number

    The starting document offset, which must be non-negative. By default, you cannot page through more than 10,000 hits using the from and size parameters. To page through more hits, use the search_after parameter.

  • sort string | array[string]

    A comma-separated list of <field>:<direction> pairs.

  • Should this request force synthetic _source? Use this to test if the mapping supports synthetic _source and to get a sense of the worst case performance. Fetches with this enabled will be slower the enabling synthetic source natively in the index.

    • * object Additional properties
  • from number

    The starting document offset, which must be non-negative. By default, you cannot page through more than 10,000 hits using the from and size parameters. To page through more hits, use the search_after parameter.

  • Hide highlight attributes Show highlight attributes object
    • A string that contains each boundary character.

    • How far to scan for boundary characters.

    • Values are chars, sentence, or word.

    • Controls which locale is used to search for sentence and word boundaries. This parameter takes a form of a language tag, for example: "en-US", "fr-FR", "ja-JP".

    • force_source boolean Deprecated
    • Values are simple or span.

    • The size of the highlighted fragment in characters.

    • An Elasticsearch Query DSL (Domain Specific Language) object that defines a query.

      External documentation
    • If set to a non-negative value, highlighting stops at this defined maximum limit. The rest of the text is not processed, thus not highlighted and no error is returned The max_analyzed_offset query setting does not override the index.highlight.max_analyzed_offset setting, which prevails when it’s set to lower value than the query setting.

    • The amount of text you want to return from the beginning of the field if there are no matching fragments to highlight.

    • The maximum number of fragments to return. If the number of fragments is set to 0, no fragments are returned. Instead, the entire field contents are highlighted and returned. This can be handy when you need to highlight short texts such as a title or address, but fragmentation is not required. If number_of_fragments is 0, fragment_size is ignored.

    • options object
      Hide options attribute Show options attribute object
      • * object Additional properties
    • order string

      Value is score.

    • Controls the number of matching phrases in a document that are considered. Prevents the fvh highlighter from analyzing too many phrases and consuming too much memory. When using matched_fields, phrase_limit phrases per matched field are considered. Raising the limit increases query time and consumes more memory. Only supported by the fvh highlighter.

    • post_tags array[string]

      Use in conjunction with pre_tags to define the HTML tags to use for the highlighted text. By default, highlighted text is wrapped in <em> and </em> tags.

    • Value is styled.

    • encoder string

      Values are default or html.

    • fields object Required
  • track_total_hits boolean | number

    Number of hits matching the query to count accurately. If true, the exact number of hits is returned at the cost of some performance. If false, the response does not include the total number of hits matching the query. Defaults to 10,000 hits.

  • indices_boost array[object]

    Boost the _score of documents from specified indices. The boost value is the factor by which scores are multiplied. A boost value greater than 1.0 increases the score. A boost value between 0 and 1.0 decreases the score.

    The period of time to wait for a response from each shard. If no response is received before the timeout expires, the request fails and returns an error. Defaults to no timeout.

  • If true, calculate and return document scores, even if the scores are not used for sorting.

  • version boolean

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

  • If true, the request returns sequence number and primary term of the last modification of each hit.

    "term": {

Run `POST /_search` to run a point in time search. The `id` parameter tells Elasticsearch to run the request using contexts from this open point in time. The `keep_alive` parameter tells Elasticsearch how long it should extend the time to live of the point in time.

    "size": 100,  
    "query": {
        "match" : {

When paging through a large number of documents, it can be helpful to split the search into multiple slices to consume them independently. The result from running the first `GET /_search` request returns documents belonging to the first slice (`id: 0`). If you run a second request with `id` set to `1', it returns documents in the second slice. Since the maximum number of slices is set to `2`, the union of the results is equivalent to the results of a point-in-time search without slicing.

  "slice": {
    "id": 0,

Get the search shards

POST /{index}/_search_shards

Get the indices and shards that a search request would be run against. This information can be useful for working out issues or planning optimizations with routing and shard preferences. When filtered aliases are used, the filter is returned as part of the indices section.

If the Elasticsearch security features are enabled, you must have the view_index_metadata or manage index privilege for the target data stream, index, or alias.

Path parameters

  • index string | array[string] Required

    A comma-separated list of data streams, indices, and aliases to search. It supports wildcards (*). To search all data streams and indices, omit this parameter or use * or _all.

Query parameters

  • 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.

  • expand_wildcards string | array[string]

    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. Supports comma-separated values, such as open,hidden. Valid values are: all, open, closed, hidden, none.

  • If false, the request returns an error if it targets a missing or closed index.

  • local boolean

    If true, the request retrieves information from the local node only.

  • 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. IT can also be set to -1 to indicate that the request should never timeout.

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

  • routing string

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

Delegate PKI authentication Added in 7.4.0

POST /_security/delegate_pki

This API implements the exchange of an X509Certificate chain for an Elasticsearch access token. The certificate chain is validated, according to RFC 5280, by sequentially considering the trust configuration of every installed PKI realm that has delegation.enabled set to true. A successfully trusted client certificate is also subject to the validation of the subject distinguished name according to thw username_pattern of the respective realm.

This API is called by smart and trusted proxies, such as Kibana, which terminate the user's TLS session but still want to authenticate the user by using a PKI realm—-​as if the user connected directly to Elasticsearch.

IMPORTANT: The association between the subject public key in the target certificate and the corresponding private key is not validated. This is part of the TLS authentication process and it is delegated to the proxy that calls this API. The proxy is trusted to have performed the TLS authentication and this API translates that authentication into an Elasticsearch access token.

External documentation
application/json

Body Required

  • x509_certificate_chain array[string] Required

    The X509Certificate chain, which is represented as an ordered string array. Each string in the array is a base64-encoded (Section 4 of RFC4648 - not base64url-encoded) of the certificate's DER encoding.

    The first element is the target certificate that contains the subject distinguished name that is requesting access. This may be followed by additional certificates; each subsequent certificate is used to certify the previous one.
