Ishan Chattopadhyaya commented on SOLR-15880:
---------------------------------------------
Are we referring to this feature as "Neural Search" [0]? I wasn't sure what
that meant, so checked it up and came across this:
https://medium.com/jina-ai/what-is-jina-and-neural-search-7a9e166608ab
"What is Neural Search? In short, neural search is a new approach to retrieving
information. Instead of telling a machine a set of rules to understand what
data is what, neural search does the same thing with a pre-trained neural
network. This means developers don’t have to write every little rule, saving
them time and headaches, and the system trains itself to get better as it goes
along."
I'm wondering if our implementation has anything to do with neural networks yet.

> 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.
