I am working on this. Thanks for the initial draft [~cpoerschke] . I have built a good understanding of HNSW and LADR, and prodding around the current Solr KnnQParser and Lucene SeededKnnVectorQuery to continue this effort.

>             Project: Solr
>          Issue Type: New Feature
>          Components: vector-search
>            Reporter: Alessandro Benedetti
>            Priority: Major

> 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)
