Mikhail Khludnev updated SOLR-6234:
-----------------------------------
    Description: 
it adds ability to call Lucene's JoinUtil by specifying local param, ie  {{ 
{!join score=...}... }}. It supports:
- {{score=none|avg|max|total}} local param (passed as ScoreMode to JoinUtil)
- -supports {{b=100}} param to pass {{Query.setBoost()}}- postponed till 
SOLR-7814.
- -{{multiVals=true|false}} is introduced- YAGNI, let me know otherwise. 
- 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  


  was:
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.
