Subject Re: question about Field Collapsing/ grouping
Date Wed, 14 Sep 2011 09:09:49 GMT
Hi Ahson,

http://wiki.apache.org/solr/FieldCollapsing
group.ngroups seems to be added as an parameter, so you may not be
needed to apply any patches.

Solr 3.3 had released the grouping feature with it, so I presume it
should already be included in it.

Regards,
Jayendra
