!Bang Syntax
You can search other sites directly from DuckDuckGo, just by using our available !bangs.
For example, if you wanted to search on Amazon.com for, "shoes" you could simply type: !amazon shoes
...which would automatically take you to Amazon.com and search for shoes...
Many of the !bangs even have short versions. Use 'a' for Amazon or 'w' for Wikipedia. For example: !a shoes or !w shoes
There are thousands of sites covered and you can even submit your own!
