Hi Jack,
Thanks for the response and link and sorry for the late reply. I am working on this part time.
I have tried various combination, with countryCode, after looking over the API documentation but I am still not able to produce results for dental offices. For example the following outputs of coffee shops for Markham, Ontario, Canada but if I change the key word "coffee" to "dentist" then results are invalid?
http://geocode.arcgis.com/arcgis/rest/services/World/GeocodeServer/findAddressCandidates?SingleLine=...
The parameter "searchExtent" is an area based on a rectangle or a square. Is there a way to get results based on a specific radius? Based on the documentation, proximity searches has a radius 50, 000 meters. Is there a way to reduce this result to 6000 meters?
My end goal is to be able to get all dental offices on a specific radius (6000 meters) based on a specif point (latitude and longitude). If there is not possible using the "findAddressCandidates" then can you point me to a direct that I should be looking into?
