Description

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.
