[Zope] Newbie-question on ZCatalog

Hi, I'm trying to build a Catalog with a report table just as the one on http://classic.zope.org:8080/Collector/tableBrowse?cfDescAndTitle=catalog That's a table with document-title, date and the first 30 words of the document-content. My problem: how can I insert the content into the ZSearch report-file? Is there a simple way just like finding out the document-url ( here it is <dtml-var "catalog.getpath(data_record_id_)"> )? Thanks for your help Marc
