[Zope] Google-like search results

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
