Timothy Potter updated SOLR-6234:
---------------------------------
Attachment: SOLR-6234.patch
Here's an updated patch for trunk. The JavaDoc on the ScoreJoinQParserPlugin
wasn't passing precommit, so I need to fix that before committing (removed it
for now).
This does not have the code from the patch Ryan posted yet ...
[~mkhludnev] You mentioned this solution would address SOLR-6357, but I'm still
seeing the same error when using scorejoin. Can you elaborate on why you think
this fixes that problem?

> 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.
