      # Get multiple documents
      #
      # @option arguments [String] :index The name of the index
      # @option arguments [Boolean] :force_synthetic_source Should this request force synthetic _source? Use this to test if the mapping supports synthetic _source and to get a sense of the worst case performance. Fetches with this enabled will be slower the enabling synthetic source natively in the index.
      # @option arguments [List] :stored_fields A comma-separated list of stored fields to return in the response
      # @option arguments [String] :preference Specify the node or shard the operation should be performed on (default: random)
      # @option arguments [Boolean] :realtime Specify whether to perform the operation in realtime or search mode
      # @option arguments [Boolean] :refresh Refresh the shard containing the document before performing the operation
      # @option arguments [String] :routing Specific routing value
      # @option arguments [List] :_source True or false to return the _source field or not, or a list of fields to return
      # @option arguments [List] :_source_excludes A list of fields to exclude from the returned _source field
      # @option arguments [List] :_source_includes A list of fields to extract and return from the _source field
      # @option arguments [Hash] :headers Custom HTTP headers
      # @option arguments [Hash] :body Document identifiers; can be either `docs` (containing full document information) or `ids` (when index is provided in the URL. (*Required*)
