      # @option arguments [List] :index A comma-separated list of index names to search; use `_all` or empty string to perform the operation on all indices
      # @option arguments [Boolean] :ignore_unavailable Whether specified concrete indices should be ignored when unavailable (missing or closed)
      # @option arguments [Boolean] :ignore_throttled Whether specified concrete, expanded or aliased indices should be ignored when throttled
      # @option arguments [Boolean] :allow_no_indices Whether to ignore if a wildcard indices expression resolves into no concrete indices. (This includes `_all` string or when no indices have been specified)
      # @option arguments [String] :expand_wildcards Whether to expand wildcard expression to concrete indices that are open, closed or both. (options: open, closed, hidden, none, all)
      # @option arguments [String] :preference Specify the node or shard the operation should be performed on (default: random)
      # @option arguments [List] :routing A comma-separated list of specific routing values
      # @option arguments [Time] :scroll Specify how long a consistent view of the index should be maintained for scrolled search
      # @option arguments [String] :search_type Search operation type (options: query_then_fetch, dfs_query_then_fetch)
      # @option arguments [Boolean] :explain Specify whether to return detailed information about score computation as part of a hit
      # @option arguments [Boolean] :profile Specify whether to profile the query execution
      # @option arguments [Boolean] :typed_keys Specify whether aggregation and suggester names should be prefixed by their respective types in the response
      # @option arguments [Boolean] :rest_total_hits_as_int Indicates whether hits.total should be rendered as an integer or an object in the rest search response
      # @option arguments [Boolean] :ccs_minimize_roundtrips Indicates whether network round-trips should be minimized as part of cross-cluster search requests execution
      # @option arguments [Hash] :headers Custom HTTP headers
      # @option arguments [Hash] :body The search definition template and its params (*Required*)
