/**
 * Helper class for handling search operations in Fess.
 *
 * 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

Doing this, our `GzipRequest` will take care of decompressing the data (if necessary) before passing it to our *path operations*.

After that, all of the processing logic is the same.

But because of our changes in `GzipRequest.body`, the request body will be automatically decompressed when it is loaded by **FastAPI** when needed.
