Yes, you can search by post code in Vantage, and once the results are available you will also see the "refine search" in the sidebar which allows you to adjust the "distance" for a radius search. The demo site is set up with US locations, so this is not as obvious for testing, but whatever you enter in "near" field, gets geocoded from Google Maps Geocode API. If you have the "Region Biasing" settings configured correctly for you location, then this will work fine. Thanks.
