[Zope] Google-like search results

[Fabio Rolando]

Hi.
I have a collection of docuements that are indexed and automaticaally 
handled by Catalog. My search results interface now give information that 
are stored in the metatypes of the documents. I have to modify the results 
interface so that a short quote of the matching documents is displayed with 
the matching words in evidence. Something like the Google results page. Is 
there any product that can help me impementing this funzionality?
Thank you all
Fabio
