[Zope-CMF] catalog and Subject metadata

[seb bacon]

This may be dumb for all I know - I've hardly used the catalog before,
inside or outside of the CMF.  

Anyway, I was expecting the Subject field of the DublinCore metadata
to be a keyword index in the catalog, but nothing from the Subject
field is being indexed at all, AFAIK.  This is on a CVS CMF.

Should Subject be a keyword index out of the box?  I've checked the
portal_catalog tool which seems to think it's indexing Subjects.  However,
the only fields that seem to be indexed at all are those returned by
the SearchableText of a content type.
