Subject [jira] [Updated] (SOLR-2824) Cross-Core Join doesn't parse fields against joining schema
Date Wed, 30 Nov 2011 01:27:41 GMT

Hoss Man updated SOLR-2824:
---------------------------

    Attachment: SOLR-2824.patch

I hacked up a test case demonstrating the problem, but ran out of time before i could try
fixing it.  (At the moment the test just demonstrates the problem of *parsing* a cross index
join, it doesn't actually try to utilize it - our Test framework does't make it easy to index/query
multiple cores in a single test)

At first glance, it seems fairly straight forward to fix the JoinQParser to get the "fromIndex"
SolrCore via the CoreContainer and then ask it for a parser to parse the nested query, but
a few things concern me:

1) should local params from the '{!join...}' expression (besides from,to, and fromIndex) be
passed to the QParser fetched from the fromIndex ?

2) Are there other bugs lurking in JoinQuery itself that need better cross-index testing?
 In particular the JoinQuery.rewrite method smells fishy.
