In a few previous PR's we restructured the ES|QL docs to make it possible to generate them dynamically. This PR just moves a few files around to make the query languages docs easier to work with, and a little more organized like the ES|QL docs. A bit part of this was setting up redirects to the new locations, so other repo's could correctly link to the elasticsearch docs.

# Vector queries [vector-queries]
|
|
|
|
Vector queries are specialized queries that work on vector fields to efficiently perform [semantic search](docs-content://solutions/search/semantic-search.md).
|
|
|
|
[`knn` query](/reference/query-languages/query-dsl/query-dsl-knn-query.md)
|
|
: A query that finds the *k* nearest vectors to a query vector for [`dense_vector`](/reference/elasticsearch/mapping-reference/dense-vector.md) fields, as measured by a similarity metric.
|
|
|
|
[`sparse_vector` query](/reference/query-languages/query-dsl/query-dsl-sparse-vector-query.md)
|
|
: A query used to search [`sparse_vector`](/reference/elasticsearch/mapping-reference/sparse-vector.md) field types.
|
|
|
|
[`semantic` query](/reference/query-languages/query-dsl/query-dsl-semantic-query.md)
|
|
: A query that allows you to perform semantic search on [`semantic_text`](/reference/elasticsearch/mapping-reference/semantic-text.md) fields.
|

## Deprecated vector queries [_deprecated_vector_queries]
|
|
|
|
The following queries have been deprecated and will be removed in the near future. Use the [`sparse_vector` query](/reference/query-languages/query-dsl/query-dsl-sparse-vector-query.md) query instead.
|
|
|
|
[`text_expansion` query](/reference/query-languages/query-dsl/query-dsl-text-expansion-query.md)
|
|
: A query that allows you to perform sparse vector search on [`sparse_vector`](/reference/elasticsearch/mapping-reference/sparse-vector.md) or [`rank_features`](/reference/elasticsearch/mapping-reference/rank-features.md) fields.
|
|
|
|
[`weighted_tokens` query](/reference/query-languages/query-dsl/query-dsl-weighted-tokens-query.md)
|
|
: Allows to perform text expansion queries optimizing for performance.
