No such thing as an "unbiased search engine"
And that is not a knock on Bing, DuckDuckGo, Google, Qwant, etc
It is a fact - every search engine is making some kind of decision about `"what is" on the web`: they have their own crawling cycles, internal rankings, ability to reach content, etc
I use Qwant most often on my personal MacBooks
Bing on my iPhone and iPad
DDG on my wife's iPhone and iPad
Google at work (because we are defaulted to Chrome with limited ability to change defaults)
Do they all return "the same" results? More-or-less ... ish
You could run something like the meta search engine searX yourself, and give it the list of other search engines to hit and then return results to you (I did for a little while ... but decided it was not yielding better enough results (for me) to keep going vs just hitting the underlying engines
