Database services to use auto complete ?

How can I use database services to implement auto complete in Orbeon ? Is there any tutorial on how to do it ?

Right now, the autocomplete can't be hooked to a database service, only to an external service you implement, referenced by URL. So instead of using the database service, I suggest you implement your own service that makes a query to the database and does the appropriate filtering, and point the autocomplete to that service.
