Best search function plugin/gem for instant rails 2.0

Hi, I'm creating a simple web app for with multiple tables my university assignment and I need to create a search function. I've heard about some search plugins and gems but I'm not sure which is the best one to use. I'm not much of a coder so if anyone could reccomend a fairly easy plugin/gem that would not require alot of configuration that would be great!

Thanks, Sam.

Try searchlogic - it is easy to use (although you say you are not a coder, so easy may be relative).
