I'm looking for suggestions on the best way to implement a full-text search on some static data on the iPhone.

Basically I have an app that contains the offline version of a web site, about 50MB of text, and I'd like for users to be able to search for terms. I figure that I should somehow build an table of ("word", reference_to_file_containing_word) or something, put that into either Core Data or just sqlite, index the "word" column, then have the search facility search the table for search terms and take the intersection of the sets of results for the terms or something.

That wouldn't allow people to search for phrases but it would be pretty easy and probably not too slow.

I'd like to just use existing SDK features for this. Should I use Core Data or sqlite?

Does anyone have any other ideas on how this could be done?

I'm a complete newbie when it comes to iOS programming and much less Core Data.
