        # Get a document count.

        # The document count only includes live documents, not deleted documents which have not yet been removed by the merge process.
        # 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 count API.

        # @option arguments [String, Array] :index A comma-separated list of data streams, indices, and aliases used to limit the request.
        #  It supports wildcards (+*+).
        #  To target all data streams and indices, omit this parameter or use +*+ or +_all+.
        # @option arguments [String, Array<String>] :h List of columns to appear in the response. Supports simple wildcards.
        # @option arguments [String, Array<String>] :s 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.
        # @option arguments [String] :format Specifies the format to return the columnar data in, can be set to
        #  +text+, +json+, +cbor+, +yaml+, or +smile+. Server default: text.
        # @option arguments [Boolean] :help When set to +true+ will output available columns. This option
        #  can't be combined with any other query string option.
        # @option arguments [Boolean] :v When set to +true+ will enable verbose output.
        # @option arguments [Hash] :headers Custom HTTP headers
