Take a look in the book DNS and BIND, 4th edition, page 476 which says
in part:
RES_AAONLY:
Requires the answer to be authorative, not from a name
server's cache. It's too bad this isn't implemented, as it
would be a useful feature. Given the BIND resolver's design,
this feature would have to be implemented in the name
server, and it's not.
So I guess you're out of luck with that at least unless and until the
BIND developers decide it's important enough to implement it.

I am not aware of any such functionality, but I believe it has been
discussed before.

``And indeed people sometimes speak of man's "bestial" cruelty, but
this is very unfair and insulting to the beasts: a beast can never be
so cruel as a man, so ingeniously, so artistically cruel.''
(Ivan Karamazov, in Dostoyevsky's 'The Brothers Karamazov')
