Thanks, that explains Reddit.

I see the same phenomenon on other smaller forums, too, though. DuckDuckGo always feels like it has a smaller database than Google, which isn't really a surprise.

I mostly use a web engine (DDG) to find web sites these days, not content. Then I use the site's search instead or just browse the navigation tree. Make everything simpler.

I much prefer to use scholar.google.com or npmjs.com for research. The URL is already in my history/bookmarks and the scoped query is more useful than the generic websearch.
