The catalog has *never* supported the kind of query you would like
to make:

  (peru and forest) or (soutamerica and forest).

This is not a CMF restriction.

To accomplish such a query, you will need to write code which unions
the result sets from two separate queries;  Topics have no plumbing
for such an idea.
