I don't think the example Michael gave will work.

Try calling your DTML method from another dtml-method using the following
syntax:
    <dtml-var "PrincipiaSearchSource()">

If this doesn't work, ZCatalog cannot index it. This is because ZCatalog
does not (yet) call DTML methods with any arguments. 

It will quite happily index properties at the moment, so a work around
is to store the output of your methods in a property and index that. Of
course in some instances this is not a suitable workaround and you may 
need to look at alternatives to ZClasses.
