All of these features are opt-out and will roll out to all users in the U.S. in English over the next few days. It’ll be available on all platforms, with the exception of Google Glass, and you can, of course, also use Google’s voice recognition to ask your questions. If you are familiar with the Gmail Search Field Trial and, of course, Google Now, you’ll have seen some of these cards pop up in your searches over the last few months. As a Google spokesperson told me, though, today’s launch only graduates a subset of the Gmail Search Field Trial and for now, the trial will continue as a test bed for new features for those who want to remain on the cutting edge. Over time, Google expects to bring more of the Field Trial feature to the rest of Google Search. Given the privacy implications and sensitive nature of some of this information, it’s interesting that Google has decided to make this feature opt-out. As Google notes, all your information is sent over encrypted connections and only visible to you when you are signed in to Google. You can always turn it off completely (look for the new “Private results” section in your search settings) or on a per-session basis by clicking on the globe icon at the top of the search results page.
