[Zope] How to display 'summary' data in ZCatalog results page?

Is this entity called 'summary' available for all DTML Document objects? If so, can I display it on my search results page? Alternatively, is there some way I can make Zope render the first 200+/- characters of the object contents itself (which I seem to be able to get)? I suspect not.
