> Key: SOLR-17813
> URL: https://issues.apache.org/jira/browse/SOLR-17813
> Project: Solr
> Issue Type: New Feature
> Components: vector-search
> Reporter: Alessandro Benedetti
> Priority: Major
> Labels: pull-request-available
> Time Spent: 1h 40m

>
> Apache Lucene implemented a version of knn vector query that provides a query
> seed to initiate the vector search (entry points in the HNSW graph
> exploration).
> See "Lexically-Accelerated Dense Retrieval"(Hrishikesh Kulkarni, Sean
> MacAvaney, Nazli Goharian, Ophir Frieder).
> From SIGIR '23: https://arxiv.org/abs/2307.16779
> With this task, we aim to add to Solr this new query, probably as an
> additional parameter of the current KNN query parser.
> The only relevant parameter is Query seed
> While the Weight seedWeight is added when rewriting the query, so no special
> care should be needed there (see
> org.apache.lucene.search.SeededKnnVectorQuery#rewrite and
> org.apache.lucene.search.SeededKnnVectorQuery#createSeedWeight)
