Given the string This is just an example string to show what I mean.
How do I check that none of the words in this string start with amp, or that one (or more) of the words start with s?
This is what the iOS contacts app does when searching in the list: It checks if the firstname or lastname start with the given search string.
The post that's supposed to be a duplicate, does not answer my question; it's just a general item about the use of regular expressions.
