With its new version, it looks like DDG does NO LONGER displays hyperlinks to Google or Bing (with the same query), when it doesn't have any result to display.
Try for a random query, like qslfcugb qslvqb ficqgv ckuq gfv zejchv qs (for example).
Any alternative? Still IxQuick (based in the Netherlands), YaCy (desktop program), or an instance of Seeks/Searx, eg
