Can I use the Directory Portal for a search outside of my geolocation?

Lets say I am in Los Angeles and I want to locate a similar business in Cleveland, Ohio. I see that you have a listings based on the geolocation, but how could i look around the country or state for that matter?  Ultimately I want a national listing directory. I see that entering a zip code is   not an option. My best guess is that I would do a "Keyword search" for something like this to work.
