----------------------------------------------------------------
Solr 7.3 has kmeans++ and fuzzyKmeans clustering. But DBSCAN clustering just to
slow I thought to be useful for the 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 decomposition are planned of for Solr 7.4, so other
clustering techniques such as PCA and LSA are on the way.
