> 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.
