For the record, I require 3 basics from the search engine:
1. Filtering by date - Day/Month/Year - if looking for specific news or a problem, it filters it down accurately.
2. No junk - I do not want to scroll through dozens of pictures and suggestions to display 10 results.
3. No local results - most of the time, I am interested in default results, local results mess it up.
Bonus: Obviously good results and ability to disable safe filtering, it blocks "disinformation".
Bing fails all of those mentioned, it displays local results, even when it is set to international. DDG displays some local results based on my IP, but it generally ignores them.
DDG - 6 results on the first screen (2 local) vs only 2 results in Bing, because of junk, both local.
When I enable local results, DDG is precise, all results from my city, Bing as well, but again DDG shows 6 results, Bing only 2.
DDG can be easily switched, In Bing I have to go through settings to change location, changing language does nothing.
So this is pretty much basics of my search testing. When something claims a private search and it throws local results at me, it throws me off.
For example when I search RAM, I want to display specs, manufacturers, not to display results of local shops selling RAM and that is exactly, what they are doing by default.
