Fraser Hess over at CISMGF.com has a great search example. You can read the post at http://www.cimgf.com/2008/11/25/adding-itunes-style-search-to-your-core-data-application/

My code based off the post is:

NSArray *searchTerms = [searchText componentsSeparatedByString:@" "];
if ([searchTerms count] == 1) { // Search in name and description
    NSPredicate *predicate = [NSPredicate predicateWithFormat:@"(name contains[cd] %@) OR (desc contains[cd] %@)", searchText, searchText];
    [self.searchFetchedResultsController.fetchRequest setPredicate:predicate];
} else { // Search in name and description for multiple words
    NSMutableArray *subPredicates = [[NSMutableArray alloc] init];
    for (NSString *term in searchTerms) {
        NSPredicate *pred = [NSPredicate predicateWithFormat:@"(name contains[cd] %@) OR (desc contains[cd] %@)", term, term];
        [subPredicates addObject:pred];
    }
    NSPredicate *predicate = [NSCompoundPredicate andPredicateWithSubpredicates:subPredicates];
    [self.searchFetchedResultsController.fetchRequest setPredicate:predicate];
}
