You merely type your search terms into the small window and hit search.I built it to compliment a great application written by ObDev called LaunchBar. SearchApp provids a quick way to launch a dialog that you can enter your search terms into.It's small, fast, and reliable. There is a dropdown that lists the possible search engines, and an editor to add your own. It comes pre-configured for Google, Yahoo, eBay, Webster, UPS, and FedEx, but you can add as many as you want. Best of all, it's free.
