If I'm prepared to look at it long enough, I can generally work out what
a Regex does, but Regex does not seem to me to be a very human-friendly,
smoothly readable language.

For this particular case, it looks OK if the probe really is a literal
such as "foo". Could you show me the code you would use for this if the
probe were an actual parameter or variable with unknown contents?

That is, what would you use to replace:

if(someString.indexOf(someOtherString)) != -1)

Thanks,

Patricia
