I couldn't find anything about it in the documentation, but it's so basic question that I guess it has been asked many times before (sorry for boring you).
If I have a single reference field, I can get the reference Id with a regular query (no need to use .include() unless I want to retrieve other fields from the "joined" collection).
Therefore, I expected that in a case of a multi-reference field, I'll get an array of reference Id's without having to use .include(). After all, I only need the the IDs which are linked to the current collection.
However, that doesn't work. It seems like the query just doesn't retrieve this reference field at all, and I'm wondering why.
