Earlier today Google held its "Inside Search" event in California, where they showed us a lot of cool new features built in (or being built in) to Google.com, both on the desktop and mobile. We were hinted at one of them earlier -- Google Places buttons and code added right into the mobile page. The final version looks pretty slick -- tap a place icon, and you're presented with a map that stays above your search results and adjusts to fit the results you're seeing.
What we didn't see coming, but is every bit as cool, is a type of query builder now built into the search box. If you use search auto-complete, you know what happens if you tap one of the suggestions -- you start a search for it. Now, you have a new choice -- a plus button that will add the term to the search box, but let you add more. Yes, it's the same as was offered in the Google Search app, but now available on the web as well. These additions are available for Android 2.2 and higher, and iOS 4 or higher. Check it out, as well as some more about the Places icons, in a couple short videos after the break.
