EasySearch.Autosuggest ignores noDocumentsOnEmpty

I have a simple EasySearch.Autosuggest and when I click it, it displays the result for “”, so it fills the drop down. That is not very cute, I would like it that they have to type at least one character before it reacts. The “event” argument is also ignored, so I can not force them to press enter or check for a keystroke.

Any ideas how I can go about this?
