Looks like you are considering hierarchical facet of some sort. Haven't looked at it in a while, but if you decide to go that way you may open up a can of worms..
I would reconsider the datastructure first to see if that is really needed. You could perhaps solve this with: <field name="group" type="string" indexed="true" stored="true" multiValued="true"/> <field name="bucket" type="string" indexed="true" stored="true" multiValued="true"/> Then you get 2 facets, bucket and group when you search. Buckets will not be grouped though..
