jQuery AutoComplete使用两个数据集？

I have recently been using jQuery for light DOM manipulation for my web application and it works great. I've now been requested to add an auto complete to a data field that the user has to fill in. The data in this field is from a very limited set of data but the user can enter that data in its full format, e.g. product name, and code format, e.g. article id. So for instance, "Panasonic DVD Player" and PAN-DV-24 are equivalent. I have recently been using jQuery for light DOM
