I only miss google as a DDG user when DDG doesn't have a tool google has to give you an automatic result, i.e. when trying to look up some unit conversion ratio like lb to kg. But when you know that is what you want there is always !g.
We do have some of those tools, at DuckDuckGo they are called "Instant Answers."
For example the query: "2 lb to kg" will bring you to this results page https://duckduckgo.com/?q=2+lb+to+kg&ia=answer
You can see all our Instant Answers here: https://duck.co/ia
If something isn't triggering for you - let us know with the feedback tool on the site!

Get that 'in last year' filter already, DDG. I think I've complained about this through feedback before.
