Mongodb view replication using [[relate]] not working

[srilekhaMarktine123]

@rwynn this is one of the excellent project which I implemented in project.

However, I have requirement where I have to join couple of collections and created a final view but unable to use relate as I create final view after doing several joins.

Something like collection a and b joined to create view a_v and then joined collection c with view a_v to create another view b_v. So this b_v how do I use relate function to create index in elasticsearch? Can you give me some approach to make this work. I need it very urgently to implement this in our code. Your response is much appreciated. Thanks in advance.
