Last summer, Google launched the search field trial for users to opt into, and have Google return results from their Gmail accounts, when relevant, when performing regular web searches. This also included flight information, and Google eventually added data from Google Drive and Calendar into the mix.
Now Google has announced the further expansion of the field trial, with users now able to search Gmail contacts from the web search box.
Google says it will also soon add data from Google+ profiles into the mix.
Google had this to say in a Google+ update:
If you’re in the Google Search field trial (g.co/searchtrial), you can now look up your Gmail contacts directly from Search. Want quick directions to your friend Brittney's house while on the move? You can use Voice Search to ask "What’s Brittney's address?" and Google will show you the address, with turn-by-turn directions in one tap on your phone. If you need quick access to your friend Joanna's phone number, just say "Joanna's phone number" and it's there; with one tap you can call her. Join the field trial at http://g.co/searchtrial and let us know what you think.
We currently support all of your Gmail contacts and we'll be adding support for G+ profiles soon.
