Yonik Seeley commented on LUCENE-4378:
--------------------------------------

bq. I'm saying I disagree with them being in the general purpose QP that we ship as "QueryParser".

What about those of us who want it?  Will you veto a patch that implements this optional functionality because you believe that those who want it are misguided?

> 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)
