Well, it should query more from Google. I often find it is almost identical from Bing, with poor results. That's the major problem. A minor one is it is very slow but I can live with that.
Why should it query more from Google for people to 'take it seriously'?
Edit:
It is through tracking that Google gets results that some people see as being superiour to those of DuckDuckGo: Google's model of you makes them think that they know what you want to see, and they give you those pages.
