Unfortunately, Safari does not currently allow you to customize the search engines available from the search bar. There are a few add-ons you can use, or you can follow the procedure below to work around Safari.
DuckDuckGo operates a server that can respond to Safari’s search requests directed at Yahoo, Google, or Bing, and send those to DuckDuckGo instead. To use it, you can either use an app to make the change, or edit your hosts file directly.
