----------------------------------------------------------------
Solr 7.3 has kmeans++ and fuzzyKmeans clustering. But DBSCAN clustering was
just too slow, I thought, to be useful for Solr users. I will try it again
sometime to see if it was just how I put things together, but it was painfully
slow compared to kmeans++.
eigen and singular value decompositions are planned for Solr 7.4, so other
clustering techniques such as PCA and LSA are on the way.
