Fwd: Solr 3.5 result grouping is failing

<Forwarding this to the nutch group as well since I'm using the nutch
indexing schema>

Hi,

I'm trying to group (field collapse) my search results on a field called
"site". The schema says that it has to be indexed: *<field name="site"
type="string" stored="false" indexed="true"/>.*
But when I try to query the results with *group.field=site&group.limit=100,
*I see only 1 group of results being returned. And the group value is null.
This seems to work on another solr instance which only has a few documents
indexed. Seems to fail on bigger indexes. Help is appreciated.

Thanks
Chethan
