Once you have played through all the profiles in your area in the match, your radius will automatically expand. Maybe that one special person lives a little further away after all and it's worth taking a look far away from your known surroundings.

Other than that, you also have the option of finding people near you in the neighborhood list outside of the match. You could also adjust your search settings a little, for example by increasing or decreasing the age. This will help you discover new people in different ways.
