JavaScript Delayed Search Like Google Instant

While working on building a search tool for a documentation site I came up with this demo. I wanted to be able to execute the search much like how Google Instant currently waits for a pause in the users typing to execute the search. This is an example of how I am accomplishing that.

This is what the demo looks like even though the code is the fun part:

Tested on Mac 10.6.6 with Firefox 3.6, Chrome 9.0, Safari 5.0, and Opera 11.01
