Description

Lucene (9.10 i believe?) has added (Float|Byte)VectorSimilarityQuery classes as alternatives to KnnVectorQuery – instead of being configured with a 'topK' they are configured with minimum similarity threshold(s) for returning results (and limiting the traversal of the graph)

This ticket tracks adding a Solr QParser for these queries.
