We're back to the general problem of prohibiting things that some people don't
see use cases for. We should really try to avoid this.

I don't look at it that way. I want to make lucene easy to use to get good
search results.
Dismissing my opinion isn't productive.

> 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)
