Jilani Shaik commented on SOLR-4970:
------------------------------------

Yesterday, We have posted a mail in mailing lists dev@lucene.apache.org and solr-user@lucene.apache.org

Actually our organization is using Solr in some projects and similar scenario which I mentioned
in description triggered us to implement this feature and we want to share the changes so
that it can be improved further if it is useful.

> Scenario: 
> We will have two categories of data, where one category will be the list of primary data
(for example products) and the other collection (it could be spread across shards) holds the
transaction data (for example product sales data). We have a search scenario where we need
to show the products along with the number of sales for each product. 
> We can do flatten the schema with all data together, But if the primary data(it could
be very less may be <10000) should be in one collection where as the transaction data(it
could be in millions) in multiple shards, then we wish to have this feature where the request
handler will search the data from one collection and the corresponding search results docs
should pass to the next query for faceting and then before writing the response merge these
together to appear the result as coming from one collection.
