[Zope-CMF] Question regarding CMF-Topic

[Robert Rottermann]

Thanks for your answer,
that eliminates the problem with sorting.

But I would also like to do something like:
(Peru and forests) or (southamerica and forests)
this I could do when I was able to select the Subjects field twice.

Is there a way to do it now?

Robert
