-   * @param {number} from - Starting offset (default: 0)
-   * @param {boolean} ignore_unavailable - Whether specified concrete indices should be ignored when unavailable (missing or closed)
-   * @param {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)
-   * @param {enum} conflicts - What to do when the delete-by-query hits version conflicts?
-   * @param {enum} expand_wildcards - Whether to expand wildcard expression to concrete indices that are open, closed or both.
-   * @param {boolean} lenient - Specify whether format-based query failures (such as providing text to a numeric field) should be ignored

-   * @param {enum} search_type - Search operation type
-   * @param {time} search_timeout - Explicit timeout for each search request. Defaults to no timeout.
-   * @param {number} size - Number of hits to return (default: 10)
-   * @param {list} sort - A comma-separated list of <field>:<direction> pairs

-   * @param {boolean} version - Specify whether to return document version as part of a hit
-   * @param {boolean} request_cache - Specify if request cache should be used for this request or not, defaults to index level setting
-   * @param {boolean} refresh - Should the effected indexes be refreshed?
-   * @param {time} timeout - Time each individual bulk request should wait for shards that are unavailable.
-   * @param {string} wait_for_active_shards - Sets the number of shard copies that must be active before proceeding with the delete by query operation. Defaults to 1, meaning the primary shard only. Set to `all` for all shard copies, otherwise set to any non-negative value less than or equal to the total number of copies for the shard (number of replicas + 1)
-   * @param {number} scroll_size - Size on the scroll request powering the update_by_query
-   * @param {boolean} wait_for_completion - Should the request should block until the delete-by-query is complete.
-   * @param {number} requests_per_second - The throttle for this request in sub-requests per second. -1 means no throttle.
