Robert Muir commented on LUCENE-4378:
-------------------------------------
I don't agree with this. Negative boosts to terms are generally undesirable,
this is really esoteric and trappy.
> QueryParsers do not support negative boosts

> Negative query boosts have been supported at the "Query" object level for a
> long time (resulting in negative scores for matching documents), but
> evidently we never updated the QueryParsers to know about this - attempting
> to specify a negative boost in the query string results in a parse error.
> we should probably add this to the parser grammer(s)
