Using a wildcard or '*' will match any character, or no character at all. "jo*n" matches: "john", "joan", and "join", "jon" or "jonathan". Or you can use "jo*" or just "j*", but it may result in "too many matches". It works better when used with first name or last name, e.g. "j* steven". To match even more, try "j* steve*" or "steve* j*".
