Original description

It would be nice to be possible to filter subdocuments in queries by their ORID.

Example: 

There exists classes Task and User, and each task contains a
list of users. Also a set of users and their ORIDs are known.

So, I would like to be able to do query that searches all tasks which
contains a given set of users by their ORID.

The query would be something like this:  "select * from Task where
users contains (orid in ['1:1', '1:2'])"
