> This issue provides a new FunctionRangeQuery, which is basically a wrapper 
> around ValueSourceScorer (retrieved from FunctionValues.getRangeScorer).  It 
> replaces ValueSourceFilter in the spatial module.  Solr has a class by the 
> same name which is similar but isn't suitable to being ported.
> Also, it includes refactorings to the ValueSourceScorer, to include 
> performance enhancements by making it work with the TwoPhaseIterator API.
> note: I posted this to LUCENE-4251 initially but then felt it's really its 
> own issue.
