Google School: Filter Google Results by Date with a URL Trick

Google can reorder search and news results from the last day, week, a few months, or entire year by adding a small string to the end of the search URL. Just add this string – &as_qdr=d – to the address bar and hit enter. You’ll get a custom drop-down box that lets you re-order results based on date.

Cool trick! And most useful too.
