Field collapsing

[Doug Steigerwald]

Being able to collapse multiple documents into one result with Solr is a big deal for us here.  Has 
anyone been able to get field collapsing (http://issues.apache.org/jira/browse/SOLR-236) to patch to 
a recent checkout of Solr?  I've been unsuccessful so far in trying to modify the latest patch to work.

Thanks.
Doug
