Google update

I Google. Really I do. But it's not perfect, and one of the imperfections that I run into all the time is that I can't search by date. It's especially frustrating because most databases do have searching by date, and they have very flexible and usable searching by date and even arranging results by date ascending or descending.
So I was happy to see that the Advanced Search page now offers the ability to search by date. It's a limited ability - the date dropdown box offers the choices "past 24 hours, past week, past month, past 2 months, past 3 months, past six months, past year." But you can tweak this in the search URL. The date search parameter is "as_qdr=" , so you can change the value of as_qdr to custom intervals by adjusting the values of "as_qdr" parameter:
d[number] - past number of days (e.g.: d10)
w[number] - past number of weeks
y[number] - past number of years
So if you wanted to search for everything added to the internet about the Steelers in the past 3 days your search url would be http://www.google.com/search?as_q=Steelers&as_qdr=d(3) .
They still have a long way to go but it's a start!
