Robert Muir commented on SOLR-1804:
-----------------------------------
Grant I am concerned about a possible BW break in Lucene trunk, that is all.
I think its strange that 3.0 and 3.1 jars give different results.
Can you tell me if the clusters are reasonable? here is the output.
{noformat}
junit.framework.AssertionFailedError: number of clusters: [
{labels=[Data Mining Applications], docs=[5, 13, 25, 12, 27],clusters=[]},
{labels=[Databases],docs=[15, 21, 7, 17, 11],clusters=[]},
