BooleanScorer - Maximum Prohibited Scorers?

[David Stimpert]

Hello,
I have found useful functionality in BooleanQuery which allows me to
specify a minimum number of matching optional terms
(i.e. setMinimumNumberShouldMatch).  I do not, however, see similar
functionality available for setting the maximum number of MUST_NOTs (i.e.
setMaximumNumberMustNotMatch).  I am starting to look into how I could
customize this functionality.  Does this seem feasible?  Do you foresee any
major challenges?  Any advice?
