-----------------------------------------------------------------------
Thanks [~jbernste] for your feedback!
We have finalised also a benchmarking blog post (that is linked in the
documentation).
So in case you want to provide your results as well, we can integrate them in
our blog post (or if you have/want to write one, add it to the references!).
In regards to the documentation I added:
"The score for a retrieved document is the approximate distance to the target
vector(defined by the similarityFunction configured at indexing time)."
I'll wait just another day and in case of no additional feedback, I proceed
tomorrow with the merge.

> This contribution introduces in Apache Solr the ability to run vector-based
> searches using native Apache Lucene data structures optimized for approximate
> nearest neighbours.
> This is the first milestone in introducing Neural Search in Apache Solr.
> More will come later.
> It builds on top of https://issues.apache.org/jira/browse/LUCENE-9004 to
> provide a:
> - *Dense Vector Field* - At moment Single valued, supporting stored, indexed
> - *Knn Query Parser* - simple query parser to run knn search on target vector
> and field
> The Dense Vector field only supports KNN searches (no range query, no field
> queries, no existence queries...)
> The Knn query parser can be used as query, filter query and rerank query.
