They represent Stuff I'have Seen (SIS) (see SIS) and introduce a new module Implicit Query (IQ) that takes advantage of the context. For example, if the user is reading an email, IQ looks at the keyword in the email and proactively do searches based on those keywords and present them on the side. They believe search in personal items is going towards Stuff I Should See.
