Open Distro for Elasticsearch is said to be working on ANN approach with a new
Lucene codec (a new codec built for ANN may be the ultimate solution)

> Vector Search in Solr (Umbrella Issue)
> --------------------------------------
>
> Key: SOLR-12890
> URL: https://issues.apache.org/jira/browse/SOLR-12890
> Project: Solr
> Issue Type: New Feature
> Reporter: mosh
> Priority: Major
>
> We have recently come across a need to index documents containing vectors
> using solr, and have even worked on a small POC. We used an URP to calculate
> the LSH(we chose to use the superbit algorithm, but the code is designed in a
> way the algorithm picked can be easily chagned), and stored the vector in
> either sparse or dense forms, in a binary field.
> Perhaps an addition of an LSH URP in conjunction with a query parser that
> uses the same properties to calculate LSH(or maybe ktree, or some other
> algorithm all together) should be considered as a Solr feature?
