Greetings :) Wildcard indexof ?

Question

Hello there...Is it possible to use a wildcard character with the IndexOf() string function? In other words if I have the string "Bob is a useless person and is not cool" ...if I wanted to get the index of this and everything between Bob and cool could change...how could I use a wildcard character to do something like this? IndexOf("Bob*cool")? Please i'm DESPERATE and cannot find this answer anywhere! Thanks, Andy
