== Neural Query Parsers
== Vector Query Parsers

There is currently one Query Parser in Solr to provide Neural Search: `knn`.
There are currently three Query Parsers in Solr to provide Vector Search:

KNN stands for k-nearest neighbors.
- `knn`: matches k-nearest neighbours (knn) documents to the target vector.
- `knn_text_to_vector`: encode a textual query to a vector using a dedicated Language Model and matches knn documents to such query vector.
- `vectorSimilarity`: matches documents whose similarity with the target vector is a above a minimum threshold.

Details are documented further in the section xref:query-guide:dense-vector-search.adoc[].
