File objects are not 'documents', although they may of course contain files
which you consider to be documents.  Since File objects can contain
*anything*, including binary executables or images, they don't define
'contents' for ZCatalog purposes.

What you might want to do is create a sub-ZClass of File dedicated to
storing your document files, and define a PrincipiaSearchSource method which
returns the contents of the object.  You could even pre-process the contents
in this method if you wanted to strip off headers or formatting or any other
bits you don't really want in your full-text search.
