How to implement autocomplete on a massive dataset

Question

I\'m trying to implement something like Google suggest on a website I am building and am curious how to go about doing in on a very large dataset. Sure if you\'ve got 1000 items

Not algorithmically related to what you are asking, but make sure you have a 200ms or more delay (lag) after the kaypress(es) so you ensure that the user has stopped typing before issuing the asynchronous request. That way you will reduce redundant http requests to the server.
