Subject [jira] [Commented] (LUCENE-3099) Grouping module should allow subclasses to set the group key per document

After FQ is relatively done/stabilized, then we should look into grouping offering collectors
for all filed types, using the infrastructure from that common module, and extending the common
module at that time if there are needs of grouping not yet met, ie merging in the GroupValue,
GroupValueSource, GroupHolder from this patch.

That makes sense to me.

> The new grouping module can only group by a single-valued indexed field.
> But, if we make the 'getGroupKey' a method that a subclass could override, then I think
we could refactor Solr over to the module, because it could do function queries and normal
queries via subclass (I think).
> This also makes the impl more extensible to apps that might have their own interesting
group values per document.
