Not quite sure of your question.
if there is a zone you want for your internal network do something like 
this.

        match-clients              { internals; };
        match-destinations      { internals; };
        allow-recursion {192.168.0.0/24;127.0.0.1;};

for external
        match-clients           { any; };
        match-destinations      { any; };
        recursion no;

This is assuming you're setting up views.
Bind and views can get complicated.
You may be better off setting up two DNS servers, one for internal and 
one for external.
I have no experience with it but its been suggested here that dnsmasq is 
very easy to configure.
