Currently we have an address geocoding service published to ArcGIS Server that is being utilized by an ArcGIS Viewer for Flex application. The service works just fine, but the end users would like for it to be more suggestive when they type in an address query. The main issue is that the geocoder does not return any search results until the entire road name has been entered. Our end users would like for it to return results even if only part of the road name is entered. I am having a hard time figuring out how to accomplish this because our reference data does not separate the road name components into individual fields like base name and suffix. All the street name information is contained in one field. I have adjusted the values for minimum match score, minimum candidate score, and spelling sensitivity, but these changes do not have the result that we are looking for.
Is returning search results based on a partial street entry something that can even be accomplished with the geocoding service, or does that type of functionality have to come from the application itself? I have seen java script applications that provide suggestive address searches, but I am not familiar with Flex at all and am unsure if that can be done.
