      # Run a search with a search template.
      #
      # @option arguments [String, Array] :index A comma-separated list of data streams, indices, and aliases to search.
      #  It supports wildcards (`*`).
      # @option arguments [Boolean] :allow_no_indices A setting that does two separate checks on the index expression.
      #  If `false`, the request returns an error (1) if any wildcard expression
      #  (including `_all` and `*`) resolves to zero matching indices or (2) if the
      #  complete set of resolved indices, aliases or data streams is empty after all
      #  expressions are evaluated. If `true`, index expressions that resolve to no
      #  indices are allowed and the request returns an empty result. Server default: true.
      # @option arguments [Boolean] :ccs_minimize_roundtrips Indicates whether network round-trips should be minimized as part of cross-cluster search requests execution. Server default: true.
      # @option arguments [String, Array<String>] :expand_wildcards The type of index that wildcard patterns can match.
      #  If the request can target data streams, this argument determines whether wildcard expressions match hidden data streams.
      #  Supports comma-separated values, such as `open,hidden`. Server default: open.
      # @option arguments [Boolean] :explain If `true`, the response includes additional details about score computation as part of a hit.
      # @option arguments [Boolean] :ignore_throttled If `true`, specified concrete, expanded, or aliased indices are not included in the response when throttled. Server default: true.
      # @option arguments [Boolean] :ignore_unavailable If `false`, the request returns an error if it targets a concrete (non-wildcarded)
      #  index, alias, or data stream that is missing, closed, or otherwise unavailable.
      #  If `true`, unavailable concrete targets are silently ignored.
      # @option arguments [String] :preference The node or shard the operation should be performed on.
      #  It is random by default.
      # @option arguments [Boolean] :profile If `true`, the query execution is profiled.
      # @option arguments [String, Array<String>] :routing A custom value used to route operations to a specific shard.
      # @option arguments [Time] :scroll Specifies how long a consistent view of the index
      #  should be maintained for scrolled search.
      # @option arguments [String] :search_type The type of the search operation.
      # @option arguments [Boolean] :rest_total_hits_as_int If `true`, `hits.total` is rendered as an integer in the response.
      #  If `false`, it is rendered as an object.
      # @option arguments [Boolean] :typed_keys If `true`, the response prefixes aggregation and suggester names with their respective types.
      # @option arguments [Boolean] :error_trace When set to `true` Elasticsearch will include the full stack trace of errors
      #  when they occur.
      # @option arguments [String, Array<String>] :filter_path Comma-separated list of filters in dot notation which reduce the response
      #  returned by Elasticsearch.
      # @option arguments [Boolean] :human When set to `true` will return statistics in a format suitable for humans.
      #  For example `"exists_time": "1h"` for humans and
      #  `"exists_time_in_millis": 3600000` for computers. When disabled the human
      #  readable values will be omitted. This makes sense for responses being consumed
      #  only by machines.
      # @option arguments [Boolean] :pretty If set to `true` the returned JSON will be "pretty-formatted". Only use
      #  this option for debugging only.
      # @option arguments [Hash] :headers Custom HTTP headers
      # @option arguments [Hash] :body request body
      #
      # @see https://www.elastic.co/docs/api/doc/elasticsearch/operation/operation-search-template
