Google introduced real-time search features in December, but it wasn’t until today that the niche got its own home at www.google.com/landing/realtime. Google has also added some tools to make the mighty river of real-time more manageable: You can narrow your search to a specific geographic area or discussion and get email updates on search topics you’re interested in. And in the opacity of a typical Google user experience, if you want to access real-time search from the homepage, good luck. You can, however, find it in the left column of Web search results by clicking on “more,” then on “updates.
