----------------------------------------------------------------
Just wondering if there is a reason not to "fix" the user's query by adding a
{noformat}*:*{noformat} (maybe implicitly), rather than throwing an Exception?
This is invariably the fix users are instructed to apply in this case, and it
does seem to be the logical implication of a pure not-query.

> 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.
