If you are trying to show documents that have facet value V1 excluding
those with facet value V1.1, then you would need to issue a query
like:
+f:V1 -f:V1.1
assuming your facet values are indexed in a field called "f". I don't
think this really has anything to do with faceting; it's just a
filtering problem.
