In PTK, PortalContent-derived classes have the method 

  def SearchableText(self):
      "text for indexing"


This returns a string concatenation of any text that should be indexed
in the catalog for a search of PortalContent in the portal.

The Portal's catalog is set up to index on the SearchableText attribute,
as well as other Dublin Core attributes.

I guess, in general, you need to define standards for getting
appropriate text for indexing from you content objects, then apply these
standards to your site.

The query/predicates stuff in ZPatterns looks like it will be much
better than this... when it lands :-)
