Thanks for the note.

Depending on what Brand Thunder bundle you are using, there may be two search boxes.

The one that can be changed is the search box at the top right of the browser, called the "chrome search". There is a small drop down on the left-side of the box that lets you pick any search-engine, or even add your own.

If you are using a bundle with the search box on the bottom left, that is fixed right now with our partner Yahoo.

Hopefully this answers your question!
