-----------------------------------------------------------------
I started testing the branch this morning. So far it looks great. Very easy to
use, just following the docs. One thing that we'll probably want to do is add
the vector field and a dynamic field type to the _default schema.
I've attached a screen shot of my first query.
Next steps I'm going to load 1 million rows and check the performance. Then
I'll scale up from there I'll report back on my findings.

> Introduce Support to K Nearest Neighbors Search

> Key: SOLR-15880
> URL: https://issues.apache.org/jira/browse/SOLR-15880
> Project: Solr
> Issue Type: New Feature
> Security Level: Public(Default Security Level. Issues are Public)
> Affects Versions: 9.0
> Reporter: Alessandro Benedetti
> Assignee: Alessandro Benedetti

> 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.
