I have a 10.3 geocoding service with suggestions enabled which is based on address points. The endpoint can be accessed here: http://gis.anaheim.net/arcgis/rest/services/AddressPointGeocoder/GeocodeServer
Everything works correctly except for the suggestions, which seem to be returning invalid matches. For example, if you test the Suggest functionality here: http://gis.anaheim.net/arcgis/rest/services/AddressPointGeocoder/GeocodeServer/suggest and type in 1240 E Diana, you get 3 suggestions: http://gis.anaheim.net/arcgis/rest/services/AddressPointGeocoder/GeocodeServer/suggest?text=1240+e+diana&category=&location=&distance=&f=html
but only one is valid (1240 E Diana Ave).
Where did the other two come from? Maybe I am misunderstanding how suggestions work, but I expected the geocoding service to query the data on the fly and only present valid matches.
