RE: Need help with a rule

["Sheahan, Paul (PCLN-NW)" <Paul.Sheahan () priceline com>]

In some cases I do know the set of characters that might follow "twenty".
Let's say I want an alert for "twenty" but not "twentyone" and that is it.
Do you think that might be possible to create a rule for?

Thanks again!

I don't think so, unless you know the whole set of characters that might
follow "twenty", such as space, period, comma, etc..
