[Zope-CMF] ZCatalog issue

[J.C.Mcnulty@open.ac.uk]

Hi all,

We have a two portals inside another portal. When we update the
portal_catalog we have to do it for each of the three portals. Sometimes if
you update it in one it will not be searchable in the other and this has to
be done manually. 

My question is, is there a way to have just one main portal_catalog and each
portal will use this catalogue instead of its own one, and can the
portal_catalog be automatically updated. 

Thanks

James McNulty
