Actually... it does work for web sites! How, you ask? You have to actually copy the highlighted text, then press the 'Search' button. Et viola, mon brav. As Del would say. I expect this will work in any app that lets you copy text. Have fun, chums.
Sadly it only works in the browser; it would be cool if I could also search with a tap in an app like, let's say Mail... :/
