UISearchDisplayController displaying results parse - ios

Question

I have got fully working UISearchDisplayController implied in my UITableView made with Parse.com. Anyway when I put to search for, I always get only results starts with that letter. I want to display every data contains that letter.
For example: I put Om into my search and it searched me only : Oman and Ombudsman . I have in my UITableView also a cell named Community . You see this word also contains om but my search don`t display anything. It displays just words staring with these letters.
Can someone help me? Thank you.

Use - (void)whereKey:(NSString *)key containsString:(NSString *)substring instead of - (void)whereKey:(NSString *)key hasPrefix:(NSString *)prefix
-(void)filterResults:(NSString *)searchTerm {
PFQuery *query = [PFQuery queryWithClassName: #"Countries"];
[query whereKey:#"CountryTitle" containsString:searchTerm];
query.limit = 50;
[query findObjectsInBackgroundWithTarget:self selector:#selector(callbackWithResult:error:)];
}
if you use hasPrefix: then the search results will be elements starting with your search string.
