Plugin to Filter Search of Resource Database?

I am building a website that will be a database of links to various websites and other resources and would like a way for visitors to refine their search of my listed resources based on the specific information they are looking for. Currently I am using All-In-One Event Calendar and I like how visitors can filter the events based on tags and Categories. I am looking for a plugin that does the same type of refined search, but for a list of links rather than events. Ideas?

Thanks so much!
