Mikhail Khludnev updated LUCENE-5868:
-------------------------------------
Attachment: LUCENE-5868.patch
attaching [^LUCENE-5868.patch]. Glue all stuff together. The significant change
is introducing a new signature in {{JoinUtil}}, you know why:
{code}
public static Query createJoinQuery(String fromField,
boolean multipleValuesPerDocument,
String toField,
NumericType numericType,
Query fromQuery,
IndexSearcher fromSearcher,
ScoreMode scoreMode) throws IOException
{code}
I added existing test in the patch. Test coverage needs to be improved.
Opinions?

> while polishing SOLR-6234 I found that JoinUtil can't join int dv fields at
> least.
> I plan to provide test/patch. It might be important, because Solr's join can
> do that. Please vote if you care!
