In my iOS application I have a really simple predicate for my fetch controller.

NSString *format = [NSString stringWithFormat:@"name like[c] '%@'", nameVar];
NSPredicate *predicate = [NSPredicate predicateWithFormat:format];
[fetchController setPredicate:predicate];

It performs basic case-insensitive name lookup. Now I'd like to change it so that I could put a number of words in search box (nameVar has the value from search box) separated by spaces and have the predicate filter the results matching all those keywords.

So if I have two names: "John Smith" and "Mary Smith" and I search for: "Smith M" I would like to have only one result but a search like that: "Sm th ith" should return both values.

Does anyone have an idea how should this be implemented?
