-The `withKnnQuery` method in `NativeQueryBuilder` has been replaced with `withKnnSearches` to build a `NativeQuery` with knn search.
-
-`KnnQuery` and `KnnSearch` are two different classes in elasticsearch java client and are used for different queries, with different parameters supported:
-
- `KnnSearch`: is https://www.elastic.co/guide/en/elasticsearch/reference/8.13/search-search.html#search-api-knn[the top level `knn` query] in the elasticsearch request;
- `KnnQuery`: is https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-knn-query.html[the `knn` query inside `query` clause];
-
-If `KnnQuery` is still preferable, please be sure to construct it inside `query` clause manually, by means of `withQuery(co.elastic.clients.elasticsearch._types.query_dsl.Query query)` clause in `NativeQueryBuilder`.
