> DDG isn't very good at searching

You can use the !g bang to search on google.

The main advantage I personally see in using DDG is to be able to directly search on sites. For instance:

  * I need to lookup foo on wikipedia: !w foo
  * I need to search for foo on amazon: !a foo
  * I need to lookup a video on foo: !yt foo
