 ## Knn query inside a nested query [knn-query-with-nested-query]

+The `knn` query can be used inside a nested query. The behaviour here is similar to [top level nested kNN search](docs-content://solutions/search/vector/knn.md#nested-knn-search):
 
-* kNN search over nested dense_vectors diversifies the top results over the top-level document
+* kNN search over nested `dense_vector`s diversifies the top results over the top-level document
 * `filter` both over the top-level document metadata and `nested` is supported and acts as a pre-filter
 
-::::{note}
-To ensure correct results: each individual filter must be either over
-the top-level metadata or `nested` metadata. However, a single knn query
-supports multiple filters, where some filters can be over the top-level
-metadata and some over nested.
