Maybe a silly answer, but isn’it a side effect of lazy loading?

Oops - I meant to say it's an NSMutableDictionary!
What might a quick stubbed example of that be? Not sure I am following. How
much speed would it generally gain?

Simple example. Init a NSMutableDictionary. For each string, compute a hash key
as the sum of all chars composing it (in a s

You can try to use that, but, basically, it is the same problem: you enumerate

Thanks. The distance is computed because the entry string is dynamic and
it's providing a distance between the title of the song and what was entered
as text. So I can't pre-compute that data and stuff into a dictionary. Each
time the method is called, the *stringValue* will be different.

I think I see what you're onto here now. So I might only have about 30 or so
keys to search through instead of all 1,777 items, and then just grab an
array (or probably a dictionary) of stuff out of that to search on...
resulting in a lot less searching to hopefully get to a potential match.

Interesting idea. The structure is that I have a grandparent with just a single
