Help with Predicate count/relationships

Subject: Help with Predicate count/relationships

hello I'm using CoreData. I've an Entity called 'Article'. It contains a
relationship (1..n)called "children" (replies to the istance). Now I would
make two predicate strings:
a) returns the number of 'article' that no contains childrens
b) return the array of 'article' that contains childrens. I've found a
@count function but I don't know how to make a predicate with it.

Thanks to all
