Why the hell do I want to see my emails in search results? I do have a search within Gmail, isn't it? It is all a trap to keep people signed in, so they can spy them more.
Do you know why we see more of "(not provided)" in our keyword analytics tool? Google automatically checks the "Stay signed in" checkbox by default, on their Gmail sign in form. Even if you take care to uncheck it, and type a wrong password or username you will be presented with the sign in form that has the "Stay signed in" re-checked again.
Several ordinary users will never notice this and they always work signed into their google account letting the evil google to merrily track them.
