             Summary: Add support for SeededKnnVectorQuery
                 Key: SOLR-17813
                 URL: https://issues.apache.org/jira/browse/SOLR-17813
             Project: Solr
          Issue Type: Sub-task
            Reporter: Alessandro Benedetti


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)
