Google made much ado of its recently created Health unit, but it didn't offer much insight into what that division would actually... well, do. Now, however, it's considerably clearer. Google Health lead David Feinberg and CNBC sources have outlined some of the ideas his team has, and they revolve around (surprise!) search for both you and your doctor. Feinberg envisions a search bar that would help doctors search medical records like they do the web. A doctor could search for "87" to find an 87-year-old patient instead of using the patient's name, as an example.
