If I search for something using Google, and don't click on a link, doesn't that mean my search was fruitless? What else do we mean by 'zero-click searches'?
Edit: Unless it's the simple '6 x 10' or 'What is the time in London', in which case, are we surprised these queries are handled by $SearchEngine? DDG does the same thing (albeit, uses a third party website and gives credit)
