Hi Nitin, You can use Streaming Expressions <https://cwiki.apache.org/confluence/display/solr/Streaming+Expressions> for Joins in SolrCloud only (For Collections Not Core).
Again this can affect you performance, I would suggest to copy fields from one collection to another any seamlessly use features like facet. Facets get difficult and complex as you use Joins ( Ref <http://lucene.472066.n3.nabble.com/Solr-6-Use-facet-with-Streaming-Expressions-LeftOuterJoin-td4290526.html> ). -- View this message in context: http://lucene.472066.n3.nabble.com/SOLR-JOIN-tp4322744p4322781.html Sent from the Solr - User mailing list archive at Nabble.com.
