How does geocode-PostGIS work to find a location?
Takes in an address as a string (or already normalized address) and outputs a set of possible locations which include a point geometry in NAD 83 long lat, a normalized_address (addy) for each, and the rating. The lower the rating the more likely the match. Results are sorted by lowest rating first.
