Subject Re: Strange NPE with SOLR-236 (Field collapsing)
Date Wed, 12 May 2010 06:22:16 GMT
Hi Eric
I catch the NPE in the NonAdjacentDocumentCollapser class and now  it does
return the data field collapsed. 

However I can not promise how accurate or correct this fix is becuase I have not
got allot of time to study all the code.

It would be best if some of the experts could give us a clue 

I made the change in
solr src java org apache solr search fieldcollapse, inner class FloatValueFieldComparator.
