Microsoft Edge changing search bar

How to change the default search engine in Microsoft Edge

These instructions are outdated- my Microsoft edge no longer has the "Add New" button for search engines

Instead of I try to follow the instructions, there is only a button to change the search engines which then brings you to only two options - bing or youtube.

If you uninstall Microsoft edge or try it with a new computer where you haven't saved any search engines like google for the search bar, you'll see what I see

Yes, those instructions are outdated.

You have to first visit the page of a search engine that supports OpenSearch, such as Google. Once you've been to a page that supports OpenSearch, then that search engine will appear in the list of available search engines.
