Edge search Change from Bing to Google

Changing search in settings ADVANCED when you click on the add new all lines are greyed out .What to do ,or what causes that?I DO Not like Bing

If I understand what you want, i.e. to add/change to a different default search provider (like Google), what seems to work is that you first have to use Edge to display that search engine's page, e.g. type in google.com in the address/search bar and let the page load. Then go back to the advanced settings and you should see Google as an option. Unless you actually go to the Google search page first, you can't use it in the settings. I read why, but have forgotten the details.
