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

[Roberto Carna]

But if I want to resolve:

foo.google.com

that doesn't exist in my google.com private zone, I don't obtain any result.

I need to tell my private BIND to forward to 8.8.8.8 all the received
*.google.com queries, except www.google.com that is the one locally
resolved.

Thanks again !!!
