If your Google search just isn't returning the quality content you want, this little URL trick might find more in-depth articles on the subject you're searching for.

Alex Chitu at Google Operating System recently discovered that Google has a section for "in-depth articles", from which it features longer posts from sites like the Wall Street Journal, New York Times, Wired, The Economist, and more. It only seems to work in the US, and it only pops up sometimes—but you can manually bring it up by adding this to the end of your search URL:

&tbs=ida:1&gl=us

It doesn't work all the time, and it's certainly a bit limiting, but it's worth a shot if Google just isn't giving you the kind of results you want.
