Curious about the lack of Vespa, especially given the thoroughness of the article and its long-time reputation. OpenSearch is also missing, but perhaps it can be considered being lumped in with Elasticsearch due to them both being based on Lucene. The products are starting to diverge, so would be nice to see, especially since it is open-source.
For the performance-based columns, would be also helpful to see which versions were tested. There is so much attention lately for vector databases, that they all are making great strides forward. The Lucene updates are notable.
