[Zope] searching

[Catonano]

Hello list, Happy New Year!

Well, I created a Z Search interface, I fill in the 
PrincipiaSearchSource field and I got back a table with results inside 
of it. 

I modified the results table so taht it gives me some LINKS to every 
file it shows, so I can even click on them and be taken to the found 
files. Fine

Now what I'd LOVE is that when I click on one of those links, the page 
that opens has got the matching strings highlighted somehow, say:

bla bla blah <strong> matched string </strong> blah bla blah


 Can anyone suggest me how?
 
 thank you all!!
 Bye
