      # Check for a document source.
      # Check whether a document source exists in an index.
      # For example:
      # +
      # HEAD my-index-000001/_source/1
      # +
      # A document's source is not available if it is disabled in the mapping.
      #
      # @option arguments [String] :id A unique identifier for the document. (*Required*)
      # @option arguments [String] :index A comma-separated list of data streams, indices, and aliases.
      #  It supports wildcards (+*+). (*Required*)
      # @option arguments [String] :preference The node or shard the operation should be performed on.
      #  By default, the operation is randomized between the shard replicas.
      # @option arguments [Boolean] :realtime If +true+, the request is real-time as opposed to near-real-time. Server default: true.
      # @option arguments [Boolean] :refresh If +true+, the request refreshes the relevant shards before retrieving the document.
      #  Setting it to +true+ should be done after careful thought and verification that this does not cause a heavy load on the system (and slow down indexing).
      # @option arguments [String] :routing A custom value used to route operations to a specific shard.
      # @option arguments [Boolean, String, Array<String>] :_source Indicates whether to return the +_source+ field (+true+ or +false+) or lists the fields to return.
      # @option arguments [String, Array<String>] :_source_excludes A comma-separated list of source fields to exclude in the response.
      # @option arguments [String, Array<String>] :_source_includes A comma-separated list of source fields to include in the response.
      # @option arguments [Integer] :version The version number for concurrency control.
      #  It must match the current version of the document for the request to succeed.
      # @option arguments [String] :version_type The version type.
      # @option arguments [Hash] :headers Custom HTTP headers
