Search NSString in line from file

Is it possible to make a function that searchs a string for an exact substring so that it will only 'return true' if the exact string if found, not as part of a larger word?

NSString* search = @"tele";
NSString* stringOne = @"telephone";
NSString* stringTwo = @"tele phone";
NSString* stringThree = @"phone tele";

What I mean is: Is it possible to search for a string in a way that the NSString 'search' would be found in strings Two and Three, but not One?

Simplest approach is to append blanks (or whatever your separators are) to front and rear of both strings, then do the search.

Try using the following function in the NSString class:

- (NSRange)rangeOfString:(NSString *)aString
