      # Render a search template.
      # Render a search template as a search request body.
      #
      # @option arguments [String] :id The ID of the search template to render.
      #  If no `source` is specified, this or the `id` request body parameter is required.
      # @option arguments [Boolean] :error_trace When set to `true` Elasticsearch will include the full stack trace of errors
      #  when they occur.
      # @option arguments [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
      #  `"eixsts_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
      #
