One thing that makes good code good is the clarity with which it conveys the intent of the original programmer to maintainers, and the proper choice of ``++indexOf++`` methods can help move code from confusing to clear.

If you need to see whether a substring is located beyond a certain point in a string, you can test the ``++indexOf++`` the substring versus the target point, or you can use the version of ``++indexOf++`` which takes a starting point argument. The latter is arguably clearer because the result is tested against -1, which is an easily recognizable "not found" indicator.
