-------------------------------------
should we add a doNext() used by both nextDoc() and advance()
> FreqFilteringScorerWrapper and min/max freq options on TermQuery

> A Solr User was asking about how specify a minimum tf when searching for a
> term (ie: documents matching "dog" at least 3 times).
> Based on a conversation with rmuir on IRC, that led me to realize that we now
> explicitly expose a general "freq()" method on Scorer, and that min/max freq
> constraints could be implemented as a general Scorer Wrapper.
> I propose that we add such a wrapper, and add
> setMinFreq(float)/setMaxFreq(float) methods to TermQuery (similar to the
> minNumShouldMatches and disableCoord type setters in BooleanQuery) that cause
> it to be used automatically.
