Opera relies on Google by default. However, it is easy to select a different search engine or add a new one. Opera's unique keyword system lets you use a custom search engine for a query without changing the default search engine.
If you prefer to use another search engine from Opera by default, you can easily do so.
Open the Opera web browser.
