Perform a search in the address bar using the search engine you want to set as your default. Select Settings and more > Settings. Select Privacy, search, and services. Scroll all the way down to the Services section and select Address bar and search. Choose your preferred search engine from the Search engine used in the address bar menu.

Bing is a Microsoft-owned alternative to Google, and thus can be used in any web browser or as an app on your smartphone. You can also set Bing as the default search engine in Chrome, Firefox, or Safari if you wish; if you use Microsoft Edge or Internet Explorer, Bing is the search engine by default.
