It wouldn't be hard to add another criteria type to CMFTopic which
does this for content of a specific type.  The current StringCriterion
just knows which catalog index it is using;  'Type' itself is one of them!
For topics like my 'how-to' one on the dogbowl,
   http://cmf.zope.org/doc/how_tos
which span content types, the metadata tool is not much help.
