Local resolution first and then public resolution for "google.com" domain

Dear Matus, maybe I have not understood very well...

I can setup a master zone as you said:

zone "www.google.com" {
type master;
file "...";

But what are the needed clauses from Bind's named.conf.options file in
order to tell "if foo.google.com is not present in the google.com
private zone, you have to forward the query to another server (public
forwarder) in order to be publicly resolved" ???

Thanks a lot again.
