Here's a nice new feature for anyone in Gmail's field trial, which brings personalized results directly into Google search. The trial, which is available only after you opt in, brings information like Gmail results, receipts, reservations, and Google Drive documents onto the search engine results page.
Today's update brings Google Calendar items into the trial. As the company put it on Google+:
We've added Calendar results to your Gmail and Drive results. You can learn your entire schedule for the day by searching for [what is on my calendar today]. Or if you'd want to know when you're meeting up with your friend Bryan for lunch, type [when am i meeting bryan].
The trial is currently available in the United States only. New users can opt in here.
