Hoss Man commented on LUCENE-4378:
----------------------------------
bq. Dismissing my opinion isn't productive.
I don't see any one dismissing your opinion, i see yonik asking you to explain
what you mean by trappy since you seem to object to a feature on principle,
when i've already listed an example of a specific usecase where the people have
asked for this to feature and functionally it does work at the
Query/Searcher/Explaination level -- it's only at the QueryParser level that
you can't use it.
bq. Right my problem with that is I think often people that want this don't
really understand the scoring system?
there are lots of things about the query parser that may not make sense to you
if you don't understand the scoring system -- that doesn't mean we don't
support them, it's up to the user to understand them if they want to use them.
As i said: i'm perfectly fine with the idea that something like this should not
be supported by default, and you should have to go out of your way to enable it
in the QueryParser -- but making people edit the grammer seems like forcing
them to go too far out of their way.

> 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)
