My suggestion is to just not use that crap and stick to searching in the browser.I just remembered that I had another question regarding this! Even if I WERE to move to another engine that isn't Chromium based, how will I redirect my searches from Windows (since y'know, they hardlocked Edge in 11) to Waterfox, or my other search engine?
There are many tools like Edge Deflector that enable what you want though.
