After the differences in agreement with twitter, Google’s Realtime Search was down in July 2011. Twitter discontinued the access to its warehouse of data and without twitter stream of results and updates, the product was less useful. Google’s real time search used to gain much traffic especially during major world events, which displayed relevant data from Twitter, Facebook and other social media services in real time.
But now Google is confident to bring back this feature and is actively working to add the data from Google+ and other real time sources. Now, we have to wait and watch when Google will start its real time search after integrating the Google plus results.
