Try searching for something niche in an otherwise popular or well indexed topic. It's insistence on basically running OR searches will fuck up any chance of getting the niche content before the twenty more generic hits.

I run into it all the time searching for anything niche. Hell, I ran into it just the other day searching for, "kingdom two crowns skull coins". DDG gives a bunch of generic crap like the 'coins' page from the wiki, bunch of skull island results, guides... generic crap that doesn't associate all search terms. Google finds a Reddit post of someone asking exactly the question I wanted answered, and even puts it ahead of the "AI" overview. Even putting in the exact text of the reddit question without quoting it in DDG still gives all the generic hits first.

The problem only gets worse the more niche the question and the more popular the main topic. It's genuinely garbage a lot of the time. Of course I still try to use it before google, but they don't make it easy.
