 * This class provides comprehensive search functionality including document search,
 * scroll search, and bulk operations. It handles search request parameter processing,
 * query building, response formatting, and search log management.
 *
 * Key features:
 * - Document search with pagination and faceting
 * - Scroll search for large result sets
 * - Document retrieval by ID
 * - Bulk document updates

This code won't be executed in your app, we only need it to *document* how that *external API* should look like.

But, you already know how to easily create automatic documentation for an API with **FastAPI**.

### Document in OpenAPI and override `Response` { #document-in-openapi-and-override-response }

If you want to override the response from inside of the function but at the same time document the "media type" in OpenAPI, you can use the `response_class` parameter AND return a `Response` object.
