A shorthand way to express this would be to ask for all managers where "employees.@count >= 5". Very easy to express, but apparently not useable, at least as formulated above, in a fetch specification. Please correct me if I'm wrong.

I, too, would like the answer to this. The one that I keep needing is 'all relatedthingies to entity where relatedthingies.attribute >= max(relatedthingies.attribute)-2' to get the ones near the top of the range.

I solved this by bringing all entities into RAM and iterating by hand, but I do not find that very satisfying.
