Ferret talk - Jul 2006 - Use of "&" kills rails -- redux

I see someone else mentioned this below, but the answer was just "use 
&&", which isn''t what I''m looking for.

I''m using acts_as_ferret in my web app, but if the user inputs certain 
symbols, like &, it kills his/her browser.  I''m running everything 
locally on OS X.  I had to reboot OS X because the crash was so bad. 
Is there a way to screen out all these user queries that will crash the 
system?
