DuckDuckGo’s Bang Syntax
Clif Reeder (via Hacker News):
The way that DDG does this is by trading off text directives for GUI/mouse interactions. Assuming you can type faster than move and click a cursor, this is a big difference. To me, its like the difference between using Vim and a GUI based text editor.
DDG calls this the bang syntax. What it allows you to do is pipe your search directly to another site’s search - for example, Amazon, Wikipedia, Google Image Search, or hundreds of other places.
I use LaunchBar search templates for this, but I can see how it might be handy when not searching from my Mac. I gave DuckDuckGo a try but went back to Google because the results seemed to be much better.
