By now you probably know about the “Search Options” feature Google introduced in May. One of its features is to limit the search results by time frame. By default the available time frames are: Any time, Past year, Past week, Recent results and Past 24 hours. Past 24 hours is nice but still far away from Real-time. What Google isn’t telling you is that you can search in the past minute and even in the past second. The trick is to change a parameter in the URL that will narrow down the time frames. ….Notice the URL parameter qdr:d. I assume qdr stands for Query Date Range (sounds about right). All you have to do to search for the query in the past minute is to change the parameter to qdr:n, and for the past second to qdr:s.
Past Minute:

cool.. but past minute would become: http://www.google.com/search?q=barack%20obama&hl=en&output=search&tbs=qdr:n
John,
Another new feature (at least I think it’s new) in Google is the “Wonder Wheel.”
It seems to be based on Jon Kleinberg’s HITS algorithm. Anyway, it’s very cool and actually a lot of fun.
I wrote a blog post about it which you can find here:
