Some search engine allow people to use URL parameters to save their settings, but in currents version of Android Brave, the browser doesn’t allow to add new seach engine via url, so it is very inconvenient to people who enabled clear data on exit or use private browsing. Brave team should consider add this feature into Brave Android.
