Thanks for your feedback.
I can't really reveal the business case here, but assume that I do need it.
We also thought about using nested documents (which answer the query need),
but didn't use it since the child is updated in a much higher rate than the
parent and we didn't want to update the parent each time.

First, parent/child in elasticsearch is built for that need. I don't see
why you need to build something else yourself.
Then, the main question is to me: "do I REALLY need relation between
documents in a NoSQL world?"
It depends on your needs but I have often seen people trying to implement
a Document oriented NoSQL solution with the same approach as relationnal
database. So, before taking that decision, check that you really need it.
(Not saying that it's not a real need in your case).
My 2 cents.

Hi,
Let's say I have 2 types - Parent & Child with a parent / child
relationship.
I want to get data that is similar to nested documents, i.e. for each
document I get from the parent I want to get all of its children as well.
What I thought of doing is to first query for the documents in the parent,
get all their IDs and then query from the child documents all those that
are children of the requested parents.
I maintain a parent field in the child document and query for children
whose parent field is any of the parents I got.
Hope I've made myself clear.
Is there a better way to achieve that?
Thanks
Ron
