Google is testing a new Gmail search feature that crawls through a user’s inbox. Security experts say the feature is not a security risk to businesses. Google is trying to add more personal information to search results. For example, typing “my flights” in Google’s search box would get flight information if an airline had forwarded an airline’s future itinerary to Gmail. For now, people have to sign up to participate, and Gmail results will be presented in a collapsed format that requires people to open to see details.”]
