Google Contacts – Search All Contacts Under Same Domain

I found a solution to this, using what Jody suggested above as a basis.

The "#" appears to be what prevents the search URL from working. Replacing it with a %23 solved the trick. Thus, use Weby to specify the following string:

http://mail.google.com/mail/%23contacts/search/%1

It's not the most efficient way, but you get results.

Export your Gmail contacts into a .csv
Extract the names from the .csv (with Google Docs)
Create a massive filter with all the names
from: -(name1 OR name2 OR name3)

This last step will probably be best done with a string/file manipulation macro/script. If you'd like to try it, I can write one in AutoHotKey.
