> 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.
