[Zope-PTK] Need help creating subfolder for news

[Valérie Aulnette]

I am trying to add the possibility to tidy news in
subfolders (in public space).
I don't know how works ZCatalog. 
I need to do like a "select distinct" in SQL but I
don't know how to do this on portal_catalog.
Help !

Thanks in advance.
Valérie.
