Google fusion tables javascript, Ajax and php

I have polygons in a Google fusion table. It has a search on the html page where you can type in an address and if it lands inside a polygon it will tell you the name of the polygon. If it the pin lands outside a polygon it will say it does not have a polygon there. What I want is a box on the side that displays the closest polygon names based on distance ( kms ). Only first 10 closest polygons would be needed. Also, if an address does not match inside a polygon to popup an info window telling you the closest polygons name but saying no match but this is the closest result. I have everything else working except for the closest polygon name results in order of kms and the info window telling you the closest polygon and kms from the searched address.
