In our application the ability to do geocodes on US and state highways is rather important. Some of these have alternate names, for example US 422 is also known as the Benjamin Franklin Highway.
Our users know it as US 422, ArcGIS knows it at Benjamin Franklin Highway. If I was using ArcGIS for desktop I could use an alternate name table, but there doesn't seem to be an equivalent feature for ArcGIS REST API. Of course I could take of this manually, but is there a way to get ArcGIS REST API to acknowledge alternate names?
Looks like you can configure a geocoder to use alternate names.
If you publish this as the service you should be able to do what you need.
This doesn't quite do what we need. We use the ArcGIS service as provided by ESRI, not one that we host.
It looks like there is no way to do object aliases on an application or account level. We would have to host our own ArcGIS server in order to do aliasing.
