jQuery UI comes with an autocomplete module that you can supply a source to (the source just outputs JSON for records that match the given thing typed). I've heard of using Redis, some cron-job-initiated indexing, and a fast service layer to populate it quickly enough that you can't tell it's coming from a request - of course, you'd have to have a redis server big enough to store however many entries you have. If that level of speed isn't important to you then the source can always come from a typical database.

This works fine as long as the vocabulary is of a reasonable size. If we are talking tens of millions of entries, it is not going to work so well, and if you have to look up terms in real time as you type, I don't know of any client/server tool that will be fast enough.
