 If you are using `ElasticsearchRestTemplate` directly and not the `ElasticsearchOperations` interface you'll need to adjust your imports as well.
 
 When working with the `NativeSearchQuery` class, you'll need to switch to the `NativeQuery` class, which can take a

-== Breaking Changes
-
-During the parameter replacement in `@Query` annotated repository methods previous versions wrote the String `"null"` into the query that was sent to Elasticsearch when the actual parameter value was `null`.
-As Elasticsearch does not store `null` values, this behaviour could lead to problems, for example whent the fields to be searched contains the string `"null"`.
-In Version 5.3 a `null` value in a parameter will cause a `ConversionException` to be thrown.
-If you are using `"null"` as the
-`null_value` defined in a field mapping, then pass that string into the query instead of a Java `null`.

-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`.
