        # Get index information.
        # Get information about one or more indices. For data streams, the API returns information about the
        # stream’s backing indices.
        #
        # @option arguments [String, Array] :index Comma-separated list of data streams, indices, and index aliases used to limit the request.
        #  Wildcard expressions (*) are supported. (*Required*)
        # @option arguments [Boolean] :allow_no_indices 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. Server default: true.
        # @option arguments [String, Array<String>] :expand_wildcards Type of index that wildcard expressions 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. Server default: open.
        # @option arguments [Boolean] :flat_settings If true, returns settings in flat format.
        # @option arguments [Boolean] :ignore_unavailable If false, requests that target a missing index return an error.
        # @option arguments [Boolean] :include_defaults If true, return all default settings in the response.
        # @option arguments [Boolean] :local If true, the request retrieves information from the local node only. Defaults to false, which means information is retrieved from the master node.
        # @option arguments [Time] :master_timeout 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. Server default: 30s.
        # @option arguments [String, Array<String>] :features Return only information on specified index features Server default: ['aliases', 'mappings', 'settings'].
        # @option arguments [Hash] :headers Custom HTTP headers
        #
