[jira] [Commented] (SOLR-15880) Introduce Support to K Nearest Neighbors Search
[ https://issues.apache.org/jira/browse/SOLR-15880?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17464962#comment-17464962 ]
Alessandro Benedetti commented on SOLR-15880:
---------------------------------------------
[~sokolov] and [~tomoko] At Sease we finally had the time to progress with the integration of the first neural search milestone in Apache Solr.
You find the Github pull request attached.
Kudos to [~eliaporciani] that made a significant contribution and is now working on benchmarks.
More will come later, but I would appreciate your feedback :)
Code is ready for review and I am finalizing the documentation.
> 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: main (9.0)
> Reporter: Alessandro Benedetti
> Assignee: Alessandro Benedetti
> Priority: Major
>
> 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.
