As per the threads Is Solr 4.0 capable of using 'join" for multiple core?
and https://issues.apache.org/jira/browse/SOLR-2272
SOLR 4.x supports join across multiple cores. We tried it and its not giving any response.
Details are as follows:
Two cores:
- proposition { stockitemid , name }
- stocks { mc , counts }
Here "mc" references "stockitemid"
My query:
{!join from=mc to=stockitemid fromIndex=stocks}
