Google says it's offering all of these details strictly for informational purposes and that you should always consult a real doctor for proper medical advice. In other words, don't try to diagnose your severe cold just through search results. However, the company did consult with a team of doctors to review symptom info and experts at Harvard Medical School and Mayo Clinic evaluated the conditions to help improve the lists. That's in addition to collected data from medical searches and doctors in Google's own Knowledge Graph.

The company also wants to know if the information it gives you in response to those queries is helpful, and will ask for you to offer feedback on the feature. The new symptoms search is rolling out on mobile over the next few days in the US, but only in English. Google says that eventually it plans to expand the tool to other countries and languages while also including answers about more symptoms.
