> it adds {{scorejoin}} query parser which calls Lucene's JoinUtil underneath. It supports:
> - {{score=none|avg|max|total}} local param (passed as ScoreMode to JoinUtil)
>  - {{score=none}} is *default*, eg if you *omit* this localparam 
> - supports {{b=100}} param to pass {{Query.setBoost()}}.
> - {{multiVals=true|false}} is introduced 
> - there is a test coverage for cross core join case. 
> - so far it joins string and multivalue string fields (Sorted, SortedSet, Binary), but not Numerics DVs. follow-up LUCENE-5868  
> -there was a bug in cross core join, however there is a workaround for it- it's fixed in Dec'14 patch.
