Filter on child types

I’m not entirely sure what you mean by the simplest query schema. Is what I posted not the simplest schema?

I’m using the online Dgraph cloud.

I don’t see the mention of the @auth directive, did you mean the cascade directive? I took that out and still no results.

EDIT: So I know it’s possible via queryHuman but the problem is that I have a really large data set so the query one takes forever and usually times out. Maybe I just need to optimize my query instead?
