[Zope-dev] Generating abstracts in ZCatalog

Hi, I'm quite new to all this Zope development but seem to be picking things up quite nicely. However, I am having a problem generating abstracts for my Search Engine. It's something that I used to be able to do quite easily in IIS / ASP but being new to Zope I can't seem to find a way how to do it automatically. Firstly, is this possible within Zope? And if so, how? Thanks in advance, and apologies if there is an obvious answer to this that I've missed (even though I did painstakingly search through the archives!)
