How radial search works
When a property search is performed by a user and they enter a search term or select a location, they'll have the ability to also choose a radius:
We take this address entered and use the Google Geocoding service to convert this address into a latitude and longitude.
We then query and return all properties that are within X miles of this lat/lng, using the co-ordinates entered under the 'Summary' tab of a property record.
The Geocoding requests performed are cached thus ensuring only one lookup is performed per location searched.
As we use the Google Geocoding service you'll need to ensure the API key you have entered under 'Property Hive > Settings > General > Map' has access to the Geocoding Service. More about this can be found here.
