        # Run an async search.
        # When the primary sort of the results is an indexed field, shards get sorted based on minimum and maximum value that they hold for that field. Partial results become available following the sort criteria that was requested.
        # Warning: Asynchronous search does not support scroll or search requests that include only the suggest section.
        # By default, Elasticsearch does not allow you to store an async search response larger than 10Mb and an attempt to do this results in an error.
        # The maximum allowed size for a stored async search response can be set by changing the `search.max_async_search_response_size` cluster level setting.
        #
        # @option arguments [String, Array] :index A comma-separated list of index names to search; use `_all` or empty string to perform the operation on all indices
        # @option arguments [Time] :wait_for_completion_timeout Blocks and waits until the search is completed up to a certain timeout.
        #  When the async search completes within the timeout, the response won’t include the ID as the results are not stored in the cluster. Server default: 1s.
        # @option arguments [Time] :keep_alive Specifies how long the async search needs to be available.
        #  Ongoing async searches and any saved search results are deleted after this period. Server default: 5d.
        # @option arguments [Boolean] :keep_on_completion If `true`, results are stored for later retrieval when the search completes within the `wait_for_completion_timeout`.
        # @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 [Boolean] :allow_partial_search_results Indicate if an error should be returned if there is a partial search failure or timeout Server default: true.
        # @option arguments [String] :analyzer The analyzer to use for the query string
        # @option arguments [Boolean] :analyze_wildcard Specify whether wildcard and prefix queries should be analyzed (default: false)
        # @option arguments [Integer] :batched_reduce_size Affects how often partial results become available, which happens whenever shard results are reduced.
        #  A partial reduction is performed every time the coordinating node has received a certain number of new shard responses (5 by default). Server default: 5.
        # @option arguments [Boolean] :ccs_minimize_roundtrips The default value is the only supported value.
        # @option arguments [String] :default_operator The default operator for query string query (AND or OR) Server default: or.
        # @option arguments [String] :df The field to use as default where no field prefix is given in the query string
        # @option arguments [String, Array<String>] :docvalue_fields A comma-separated list of fields to return as the docvalue representation of a field for each hit
        # @option arguments [String, Array<String>] :expand_wildcards Whether to expand wildcard expression to concrete indices that are open, closed or both.
        # @option arguments [Boolean] :explain Specify whether to return detailed information about score computation as part of a hit
        # @option arguments [Boolean] :ignore_throttled Whether specified concrete, expanded or aliased indices should be ignored when throttled
        # @option arguments [Boolean] :ignore_unavailable Whether specified concrete indices should be ignored when unavailable (missing or closed)
        # @option arguments [Boolean] :lenient Specify whether format-based query failures (such as providing text to a numeric field) should be ignored
        # @option arguments [Integer] :max_concurrent_shard_requests The number of concurrent shard requests per node this search executes concurrently. This value should be used to limit the impact of the search on the cluster in order to limit the number of concurrent shard requests Server default: 5.
        # @option arguments [String] :preference Specify the node or shard the operation should be performed on (default: random)
        # @option arguments [String] :project_routing Specifies a subset of projects to target for the search using project
        #  metadata tags in a subset of Lucene query syntax.
        #  Allowed Lucene queries: the _alias tag and a single value (possibly wildcarded).
        #  Examples:
        #   _alias:my-project
        #   _alias:_origin
        #   _alias:*pr*
        #  Supported in serverless only.
        # @option arguments [Boolean] :request_cache Specify if request cache should be used for this request or not, defaults to true Server default: true.
        # @option arguments [String] :routing A comma-separated list of specific routing values
        # @option arguments [String] :search_type Search operation type
        # @option arguments [Array<String>] :stats Specific 'tag' of the request for logging and statistical purposes
        # @option arguments [String, Array<String>] :stored_fields A comma-separated list of stored fields to return as part of a hit
        # @option arguments [String] :suggest_field Specifies which field to use for suggestions.
        # @option arguments [String] :suggest_mode Specify suggest mode Server default: missing.
        # @option arguments [Integer] :suggest_size How many suggestions to return in response
        # @option arguments [String] :suggest_text The source text for which the suggestions should be returned.
        # @option arguments [Integer] :terminate_after The maximum number of documents to collect for each shard, upon reaching which the query execution will terminate early.
        # @option arguments [Time] :timeout Explicit operation timeout
        # @option arguments [Boolean, Integer] :track_total_hits Indicate if the number of documents that match the query should be tracked. A number can also be specified, to accurately track the total hit count up to the number.
        # @option arguments [Boolean] :track_scores Whether to calculate and return scores even if they are not used for sorting
        # @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] :version Specify whether to return document version as part of a hit
        # @option arguments [Boolean, String, Array<String>] :_source True or false to return the _source field or not, or a list of fields to return

        # @option arguments [String, Array<String>] :_source_includes A list of fields to extract and return from the _source field
        # @option arguments [Boolean] :seq_no_primary_term Specify whether to return sequence number and primary term of the last modification of each hit

        # @option arguments [Integer] :from Starting offset (default: 0)
        # @option arguments [String, Array<String>] :sort A comma-separated list of <field>:<direction> pairs
        # @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
