> We should at least in Lucene 4.0 remove the hack in BooleanFilter that allows pure negative
Filter clauses. This is not supported by BooleanQuery and confuses users (I think that's the
problem in LUCENE-3450).
> The hack is buggy, as it does not respect deleted documents and returns them in its DocIdSet.
> Also we should think about disallowing pure-negative Queries at all and throw UOE.
