Yonik Seeley commented on SOLR-2824:
------------------------------------
bq. 1) should local params from the '{!join...}' expression (besides from,to,
and fromIndex) be passed to the QParser fetched from the fromIndex ?
defType is the only local param that would have an impact on the foreign
qparser.
But... all the request parameters should be available to the foreign qparser.
b1. 2) Are there other bugs lurking in JoinQuery itself that need better
cross-index testing? In particular the JoinQuery.rewrite method smells fishy.
Yep!
