Hey ALL,
i created a custom locator in ArcGIS 10.3 based on the General.lot.xml. In this XML File I added serveral AliasNames for Cities, States, etc. I published this service as a geocoding service with Suggestions enabled.
Well, I can actually find everything with the right name from the attributtable. For example for New York, if I type in "Ne" it will automatically find New York. But I cant find the AliasName "NY". This is only possible by using the "FindAdressCanditates" instead of Suggest.
So I tried almost erverything. Even in the Esri White Paper, inculding the tutorial it is not working.

So do you have any " Suggestions"
