Hoss Man commented on LUCENE-3395:
----------------------------------

bq. Because if we hook it straight into this query, then someone will want it 
in SpanTermQuery, and PayloadTermQuery, and PhraseQuery, and their own 
queries???...

They might -- but like i said, i was focused on what seemed like the 
common/simple case. "make the common case easy, and the uncommon case 
'possible'"

bq. Yes! I think we should make a query that wraps another query to do this? 
Similar to ConstantScoreQuery?

I'm totally on board with the idea, i just don't really understand what the 
implementation should look like -- not because i don't think it's possible, i 
just don't personally understand how to write it.  Would the weight of the 
wrapper query just proxy directly to the inner query for all of the methods 
except scorer(..) ?

> 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.
