[Zope] HELP

I have just installed the Zope Server on my NT and have gone through the tutorial about building the Job_Board. All works OK, but I am at a bit of a loss as to HOW I can make the SEARCH open. So that if I just wanted to see say all the jobs with Programmer in the description. For example can I make a wild-card search ie Pr* and this to return all jobs with the first two letters Pr Thanks Norman
