You can also use this action instead of the websearch plugin. http://tr.im/EDqO It takes text entered in QS text entry mode and sends it to yubnub as a search.
If you don't know yubnub, read about it here: http://tr.im/D4Ak. But its basically a command line for the web. Uses prefixes to define searches. So: "g Quicksilver" googles Quicksilver "gim poodles" does a google image search for poodles "wp Persian Empire" Wikipedia searches for the Persian empire There's also some cool extras like gimyim splits your browser view into two vertical windows, the left side is a google image search and right side a yahoo image search and on and on and on. There's hundreds, if not thousands. And its easy to make your own at yubnub.org One QS action, the whole web.
