Count search results

POST /{index}/_count

Get the number of documents matching a query.

Path parameters

  • index string | array[string] Required

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

Query parameters

  • allow_no_indices boolean

    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.

  • analyzer string

    Analyzer to use for the query string. This parameter can only be used when the q query string parameter is specified.

  • analyze_wildcard boolean

    If true, wildcard and prefix queries are analyzed. This parameter can only be used when the q query string parameter is specified.

  • default_operator string

    The default operator for query string query: AND or OR. This parameter can only be used when the q query string parameter is specified.

    Values are and, AND, or, or OR.

  • df string

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

  • 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.

  • ignore_throttled boolean

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

  • ignore_unavailable boolean

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

  • lenient boolean

    If true, format-based query failures (such as providing text to a numeric field) in the query string will be ignored.

  • min_score number

    Sets the minimum _score value that documents must have to be included in the result.

  • preference string

    Specifies the node or shard the operation should be performed on. Random by default.

  • routing string

    Custom value used to route operations to a specific shard.

  • terminate_after number

    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.

  • q string

    Query in the Lucene query string syntax.
