How to search for items that contain child notes, particularly in a certain collection? I tried a saved search where:


Collection is [the collection I want], AND
Child Note does not contain [null]

This returns all items in the collection. (I achieved the null, by leaving it blank). I also tried just Notes, instead of Child Note. When I tried leaving a space instead of null, it fails to return any items.

Obviously, what we be the most useful here is to have an option in the search function that allowed:

Child Note exists or
Child Note Does Not exist.

Ideas?

Thanks!
