We have been working on creating scoring profiles for our search. We need a way to "bury" or give "negative" boosts to some fields in case of types of scoring function "Magnitude", "Freshness", "Tags". We noticed that we cannot add a negative value for boost. Is there any other way to achieve this kind of behavior (burying results based the field) 
We cannot use $OrderBy because it takes precedence over the scoring profile.

Please advise. Thanks!
