I have done it by extending the solr join plugin. Needed to override 2
methods from join plugin and it works out.

Thanks,

Hello,

There is no much progress on https://issues.apache.org/jira/browse/SOLR-8297
Although it's really achievable.

Cross collection join in Solr 5.x

[Shikha Somani]

Greetings,


Background: Our application is using Solr 4.10 and has multiple collections all 
of them sharded equally on Solr. These collections were joined to support 
complex queries.


Problem: We are trying to upgrade to Solr 5.x. However from Solr 5.2 onward to 
join two collections it is a requirement that the secondary collection must be 
singly sharded and replicated where primary collection is. But collections are 
very large and need to be sharded for performance.


Query: Is there any way in Solr 5.x to join two collections both of which are 
equally sharded i.e. the secondary collection is also sharded as the primary.


Thanks,
Shikha
