Google quietly announced on Google+ an upgrade to their field test of showing your Gmail related content in your search results.
Now instead of showing just flight results and your emails, it now will show your restaurant reservations, your hotel bookings, your event tickets and even order receipts. All you need to do is search for things like [my orders], [my reservations], [my flights] and so on.
Here are some screen shots of how the results may look:




Now, again, this is only available to limited users. U.S. users on basic gmail accounts, not Google Apps users, who opt into the field trial at this URL.

Yay! I participate in another trial where I tell Google every time I take a dump. Googlers keep track of them with charts and all for my benefit. What would I do without Googlers?

Another good reason to not use Gmail or Google+, does anyone else find this way OTT?

I hope they allow user's to easily opt-out. The emails I exchange with customers are not high-security, but they are confidentials and I would be quite upset to see some of them popping in my serp when I speak to a customer. I remember the early days of Google Desktop: I was so excited about it that I quickly presented it to a customer, only to realize that I was showing my client a lot of details about my private life that I was not intending him to learn about !
