Thanks. As I said, I already read that but it doesn't give any
examples on how to format subqueries. Anyway, I ended up adding a
helper method to my subclass after all. It returns a single array of
keywords, which I can examine using a predicate with format (ANY

Hello,
I'm trying to understand how to use subquery expressions, but I just

Well, NSArray has a method called containsObject:
