NSPredicate with OR returning error

I have a problem with the following predicate:

    NSPredicate *predicate = [NSPredicate predicateWithFormat:@"(creatorUserRecordID == %@) OR (toUser == %@)", userId, userId];

When I use it in query CKQuery *query = [[CKQuery alloc] initWithRecordType:@"Message" predicate:predicate]; I have an error that says: 'CKException', reason: 'Unexpected expression'.

When I use these two seperately like this:

   NSPredicate *predicate1 = [NSPredicate predicateWithFormat:@"(creatorUserRecordID == %@)", userId];
NSPredicate *predicate2 = [NSPredicate predicateWithFormat:@"(toUser == %@)", userId];

And then performing query with one of these predicates it works fine. I also tried using NSCompoundPredicate but the result is always the same... Any ideas?

The documentation for CKQuery lists all of the valid predicate syntax. Oddly, under "Basic compound predicates" it lists NOT, AND, and &&. OR and || are not listed and apparently are not supported for CloudKit query predicates.
