Since 2011 I have been working at an obscure web startup called Google. I’ve been working on various search projects, some of which have seen the light of day.
One project I am particularly proud of is called symptom search. A lot of people use Google to search for their symptoms. Sometimes, it may even be time-critical or life threatening (such as a query for [chest pain]).
To help users better understand the medical conditions associated with their search terms, symptom search shows you a list of conditions most relevant to your search terms when you seem to be searching for information about medical symptoms.
We launched this is February 2012 and it has been helping many users find information about their symptoms.
