      # @option arguments [List] :ids A comma-separated list of documents ids. You must define ids as parameter or set "ids" or "docs" in the request body
      # @option arguments [Boolean] :term_statistics Specifies if total term frequency and document frequency should be returned. Applies to all returned documents unless otherwise specified in body "params" or "docs".
      # @option arguments [Boolean] :field_statistics Specifies if document count, sum of document frequencies and sum of total term frequencies should be returned. Applies to all returned documents unless otherwise specified in body "params" or "docs".
      # @option arguments [List] :fields A comma-separated list of fields to return. Applies to all returned documents unless otherwise specified in body "params" or "docs".

      # @option arguments [Boolean] :realtime Specifies if requests are real-time as opposed to near-real-time (default: true).
      # @option arguments [Number] :version Explicit version number for concurrency control
      # @option arguments [String] :version_type Specific version type
      #   (options: internal,external,external_gte,force)

      # @option arguments [Hash] :headers Custom HTTP headers
      # @option arguments [Hash] :body Define ids, documents, parameters or a list of parameters per document here. You must at least provide a list of document ids. See documentation.
