Is there a command-line equivalent to "Only return exact matches"?

[jonathan soong]

Hi
I would like to be able to search my keyserver from the command line 
with the "Only return exact matches" option that exists on the webserver.

Is this possible?

e.g say there are 3 keys on my server:
key-1
key-2
key-3

gpg --keyserver localhost --search-keys key-2
returns all three keys!

Using "=" doesn't work (i presume this is only for importing keys).
?

Any suggestions would be most welcome.

thanks.
