But anyway, I used ddg too, and it gave me that link among the first results, which is weird. I thought their search was reproducible, but turns out it's not, just like google...

sometimes I navigate to a result in the same tab, but just before clicking I notice another result that could also be relevant. then I navigate back, and now the results are somewhat different, usually the result I was looking at being omitted, and with a different order too. after that reloading it always gives the same results.
