On: Solr’s Dense Vector Search for indexing and searching dense numerical vectors

[tarr11]

SOLR is using Lucene’s approximate nearest neighbor (ANN) implementation.

This site has some nice information on how ANN performs for vector search.

There is more relevant benchmark of vector search engines end-to-end, not just algorithms: https://qdrant.tech/benchmarks/

Thanks!
