        # "Flush" the index or indices.
        #
        # The "flush" operation clears the transaction log and memory and writes data to disk.
        # It corresponds to a Lucene "commit" operation.
        #
        # @note The flush operation is handled automatically by Elasticsearch, you don't need to perform it manually.
        #
        # @option arguments [List] :index A comma-separated list of index names; use `_all` or empty string for all indices
        # @option arguments [Boolean] :force TODO: ?
        # @option arguments [Boolean] :full TODO: ?
        # @option arguments [String] :ignore_indices When performed on multiple indices, allows to ignore `missing` ones
        #                                            (options: none, missing)
        # @option arguments [Boolean] :refresh Refresh the index after performing the operation
        #
