Dantes The Kagi screenshot and link you posted, you are searching in News. In the other search engines, you are searching the whole web, so it's expected that results would be quite different - and they are much closer to Bing's news search in that case.
Web search should get you the results you were looking for, or those that "make sense" given the terms:

That said, it would perhaps be better if News does not show results for this query, or gives a hint to search Web instead, similar to DDG in this case. That is something we could investigate & consider.
