Here is a screenshot of when Google went real-time when I searched. Well, that was just the Twitter updates, running live on the Google Search Page. And according to Google, there is more to real-time search than just Twitter. With real-time search Google is promising to give us the most relevant fresh information about what we search online, from news to tweets
You also have an option to control what result appear on your search page. You can go to the Option Tab on your Google Search Page and set your search from “Anytime” to “Latest” Following screenshot shows you how the search page appears when you set your options to latest.
You can also set your options to “Updates” mode. When you set your Search Options to “Updates” mode Google will give you only the most current real-time updates like Twitter. Right now I see only Twitter running on the search page. I am not sure if that is because Twitter is popular or right now Google can get updates only from Twitter. I would love if Google could give me the live feed of the most recent happening online from any site or web service, in connection with what I am searching.
