Google has launched a very interesting new search option, with its Twitter archive. What this does is let users search for a topic, and look at all available tweets about that topic in chronological order. If you want to see tweets about President Obama for example, you can do so by going to any year, month, or day and seeing what was said about him on Twitter. Google can do this since it has access to Twitter's info, which allows Google to index its real-time Twitter results. A Google spokesperson tells WebProNews it would be possible to do something similar with other sites through PuSH.

To me, while this is an interesting way of searching Twitter (in fact, I called it what Twtiter search should be), it gets even more interesting if you consider that Google is developing a system for sites to push content to Google in real-time, via PubSubHubbub (or PuSH). Google's Matt Cutts spoke with WebProNews about potential PuSH integration recently (read about it more here):

Will Google make it an option to browse entire archives of sites in a similar fashion to what it is doing with Twitter? This could be a quite useful feature, and it would certainly fall along the lines of "organizing the world's information." Let's say I remember reading a New York Times article several months back that I'd like to reference in one of my own articles, but I can't remember what it was called exactly, and I have a hard time finding it through a traditional web search. Being able to drill down into the archives in this way could make the search process much more helpful - a better user experience.

Of course most content sites have their own search features (sometimes even provided by Google), and you could try using that, but quite frankly these site search features aren't always that great. In fact, they're very often terrible. Google knows search, and it is still the most dominant search destination. It would make a ton of sense for such an option to be available.

I reached out to Google to see if this was a potential option. "The scenario described is indeed possible but we don't have anything to announce today," a Google spokesperson tells me. To be clear, when he says "possible," he's referring to the technology making such a scenario possible. As he said, there's no announcement, and this may not even be on Google's list of things to do. But, you never know. 

Google Labs already has a timeline feature for news.
