Uwe Schindler updated LUCENE-3451:
----------------------------------

    Attachment: LUCENE-3451.patch

Simple patch for trunk:
- Disables the default full-1 bitset if no required/optional clauses
- Moves the Prohibited clauses at the end. The order is now: SHOULD, MUST, 
MUST_NOT; I am not sure if this is correct and conforms to BooleanScorer2 (I 
don't understand BooleanScorer2). Does somebody know in which order clauses are 
applied in BooleanScorer2?

> Remove special handling of pure negative Filters in BooleanFilter 
> (inconsistentToBQ+broken)

> 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.
