> Change to QueryParser to default to using new ConstantScoreRangeQuery in preference to
RangeQuery
> for range queries. This implementation is generally preferable because it 
> a) Runs faster 
> b) Does not have the scarcity of range terms unduly influence score 
> c) avoids any "TooManyBooleanClauses" exception.
> However, if applications really need to use the old-fashioned RangeQuery and the above
> points are not required then the  "useOldRangeQuery" property can be used to revert to
old behaviour.
> The patch includes extra Junit tests for this flag and all other Junit tests pass
