Improve search in UISearchDisplayController - iphone

Question

I would like to improve research within my UITableViewController.
Now i have an NSMutableArray like this:
NSMutableArray *array = [[NSMutableArray alloc] initWithObjects:#"the dog is brown",#"the cat is red",#"the mouse is grey"];
Now if I write in my searchbar for example: "the cat", the table will show "the cat is red" and it is ok.
But if I write: "cat red", the table will be empty.
What can I do to improve this?
so it becomes like making the search now:
-(void)loadArray {
arraySearch = [[NSMutableArray alloc] initWithCapacity:[array count]];
[arraySearch addObjectsFromArray: array];
}
-(void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText {
[arraySearch removeAllObjects];
for (int z=0; z<[array count]; z++) {
if ([[array objectAtIndex:z] rangeOfString:searchText options:NSCaseInsensitiveSearch].location !=NSNotFound) {
[arraySearch addObject:[array objectAtIndex:z]];
}
[self.tableView reloadData];
}
Thanks to all.
I FOUND the solution and I would like to share it with you:
-(void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText {
[arraySearch removeAllObjects];
NSArray *listItems = [searchText componentsSeparatedByString:#" "];
NSMutableArray *arrayPredicate = [NSMutableArray array];
for (NSString *str in listItems) {
if ([str length] > 0) {
NSPredicate *pred = [NSPredicate predicateWithFormat:#"self contains [cd] %# OR self contains [cd] %#", str, str];
[arrayPredicate addObject:pred];
}
}
NSPredicate *predicate = [NSCompoundPredicate andPredicateWithSubpredicates:arrayPredicate];
[arraySearch addObjectsFromArray:[array filteredArrayUsingPredicate:predicate]];
[self.tableView reloadData];
}

Answer 1

-(void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText {
[arraySearch removeAllObjects];
//Break the sentence into words
NSArray *listItems = [searchText componentsSeparatedByString:#" "];
//Iterate each word and create predicate statement
NSMutableArray *predicatesArray = [NSMutableArray array];
for (NSString *str in listItems) {
[predicatesArray addObject:[NSString stringWithFormat:#"SELF like[c] %#",str]];
}
//Concatenate predicate statements by conditional OR
NSPredicate* predicate = [NSPredicate predicateWithFormat:[predicatesArray componentsJoinedByString:#" OR "]];
//Filter the array against matching predicate
[arraySearch addObjectsFromArray:[array filteredArrayUsingPredicate:predicate]];
[self.tableView reloadData];
}
