Google has actually had real-time search for a while now, and has been improving it periodically. You may have read my previous post from May comparing 10 different real-time search engines, which included Google’s offering.

To recap, as they say in the embedded “How to” video, Google Realtime allows you to search real-time content from across the web. Sources include news stories, blog posts and social networks such as Twitter, Facebook, Google Buzz and Friendfeed. The real-time stream constantly and automatically refreshes, feeding in live content as it’s posted to the web.

Google Realtime features now include:

• The ability to look back in time to view updates from the past.
• The ability to refine your search by location – by town, state or country.
• The ability to browse a conversation (on Twitter for instance), to see how it developed over time.
• The ability to set up Google Alerts for real-time updates.

Personally, I really like the addition of being able to refine search by location. As in my previous real-time search engine comparison post, I searched under a favourite topic of mine, cleantech, and then refined the search just to Australia.  It came up with some interesting and useful results for me. I’ve previously said, as it’s not a new feature, that I also like the ability to be able to search historically. This remains true.

What are your thoughts on Google Realtime Search? Have you found yourself using it yet? Is it useful enough for you, or do you use another real-time search engine? Do you use real-time search at all?

Check the embedded video for the full set of new features in more detail and how to use them.

Thanks @warlach via @andrewsayer for the heads up this morning.
