jQuery livesearch and rails

I'm trying to implement some live search function on my index view. I found this plugin开发者_开发知识库 http://www.mikemerritt.me/blog/livefilter-1-3-jquery-plugin/ but can't adapt to rails. I'm trying to reproduce the demo but can't make it work. can someone explain how to adapt the demo to rails (3.1) environment. Thanks

you could also use jQuery-UIs autocomplete. there are a ton of questions / tutorials and i think even gems to feed this autocomplete from a rails backend.
