Ahhh... Got it working now. Thanks. :) Not sure I know how to activate
ZCatalog searching though, or if it is on all the time; the example only
mentions ZCatalog once when it deletes it. What determines if a search
is a raw object-database search and when it uses the ZCatalog?
Always returning the objects is going to a bit slow, though. Couldn't
it just return the Pluggable Brains if you search the ZCatalog; or at
least have an option to only return them?
