I have an array of data, many records, each with several fields... Like an
iTunes library.

I need to crate dumb playlists (user selected records from the main library)

And smart playlists (criteria-enforced records form the main library)

When viewing wither the library, a playlist or smart playlist, I need the
search field to be able to narrow this down.

In the past for simple tables/searches I have used an NSArrayController and
the search field has been tied to the predicate with bindings.

How would I best do it in this case since I think the smart playlist is
itself a predicate-based filter.

Any sample code on this would be most useful.

I am unsure about using just a mutable array or CoreData.

Thanks,

Trygve
