So, I opened up the Abstract Tree example and that's exactly what I

that have no parents, and that's exactly what Abstract Tree does
and I see that the "parent == nil" as the fetch predicate is what
does that, but I'd also like to make it searchable so that when you
search for a string that's, for example, in a third- or fourth-
level child it will display that child and any children it has, but
none of its parents. I can make it do that, but the only way I've
been able to get it to work is to remove the "parent==nil" in the
fetch predicate line, so that when the search box is empty it
displays all of the objects of that entity type, not just the ones
with no parents. Any ideas on how to eat my cake and have it too?
Put back the 'parent==nil' predicate when the search box is empty
(when there's no other predicate).

Unfortunately, I don't know how to do that during runtime.
