I have a simple JQuery Autocomplete with a list from the database. My question is not of technical nature, but of usability.
How do you respond to a user pressing the Enter key when the search key is incomplete.
I have three items, ABC ABD and ACE.
I typed AB and two items appeared, but I pressed Enter instead of selecting the specific item from the list using the mouse.
Commonly, it will throw an exception. I am thinking of handling it with no response, or give him a feedback of "No customer found.".
