        # Get index information.
        # Get high-level information about indices in a cluster, including backing indices for data streams.
        # Use this request to get the following information for each index in a cluster:
        # - shard count
        # - document count
        # - deleted document count
        # - primary store size
        # - total store size of all shards, including shard replicas
        # These metrics are retrieved directly from Lucene, which Elasticsearch uses internally to power indexing and search. As a result, all document counts include hidden nested documents.
        # To get an accurate count of Elasticsearch documents, use the cat count or count APIs.
        # 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 an index endpoint.
        #
        # @option arguments [String, Array] :index Comma-separated list of data streams, indices, and aliases used to limit the request.
        #  Supports wildcards (+*+). To target all data streams and indices, omit this parameter or use +*+ or +_all+.
        # @option arguments [String] :bytes The unit used to display byte values.
        # @option arguments [String, Array<String>] :expand_wildcards The type of index that wildcard patterns can match.
        # @option arguments [String] :health The health status used to limit returned indices. By default, the response includes indices of any health status.
        # @option arguments [Boolean] :include_unloaded_segments If true, the response includes information from segments that are not loaded into memory.
        # @option arguments [Boolean] :pri If true, the response only includes information from primary shards.
        # @option arguments [String] :time The unit used to display time values.
        # @option arguments [Time] :master_timeout Period to wait for a connection to the master node. Server default: 30s.
        # @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
        #
