        # Update index settings.
        # Changes dynamic index settings in real time.
        # For data streams, index setting changes are applied to all backing indices by default.
        # To revert a setting to the default value, use a null value.
        # The list of per-index settings that can be updated dynamically on live indices can be found in index module documentation.
        # To preserve existing settings from being updated, set the +preserve_existing+ parameter to +true+.
        # NOTE: You can only define new analyzers on closed indices.
        # To add an analyzer, you must close the index, define the analyzer, and reopen the index.
        # You cannot close the write index of a data stream.
        # To update the analyzer for a data stream's write index and future backing indices, update the analyzer in the index template used by the stream.
        # Then roll over the data stream to apply the new analyzer to the stream's write index and future backing indices.
        # This affects searches and any new data added to the stream after the rollover.
        # However, it does not affect the data stream's backing indices or their existing data.
        # To change the analyzer for existing backing indices, you must create a new data stream and reindex your data into it.
        #
        # @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 [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+.
        # @option arguments [String, Array<String>] :expand_wildcards 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+. Server default: open.
        # @option arguments [Boolean] :flat_settings If +true+, returns settings in flat format.
        # @option arguments [Boolean] :ignore_unavailable If +true+, returns settings in flat format.
        # @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 [Boolean] :preserve_existing If +true+, existing index settings remain unchanged.
        # @option arguments [Time] :timeout Period to wait for a response. If no response is received before the
        #   timeout expires, the request fails and returns an error. Server default: 30s.
        # @option arguments [Hash] :headers Custom HTTP headers
        # @option arguments [Hash] :body settings
