Date Mon, 15 Feb 2016 10:52:19 GMT

Tommaso Teofili commented on LUCENE-6968:
-----------------------------------------

since this has also been mentioned in SOLR-7739 maybe the LSH filter can be used to create
a Lucene nearest neighbour Classifier which uses such filter (instead of the existing k nearest
neighbour one).
