This is true. Unfortunately DDG is flatly not interested in offering paginated results, if this 2 year old post by the staff member 'moollaza' on Reddit still applies.
My post there as 'the_minion_in_red' details how turning off "Auto-Load" works inconsistently depending on how you scroll, anyway - a behaviour which I see is still present and incorrect today.
And the 'lite' and 'html' views I suggest for the benefit of another poster, I don't much like because they're doing something to make the address bar URL not change so I can't easily bookmark a search.
DuckDuckGo is using the infamous "More Results", essentially infinite scroll. Until that changes Im not using DuckDuckGo.
