Right this points out one of the differences between the two. Google has instant results that appear while you type so when I wanted Chinese food I started typing and just stopped when Google results appeared relevant which was actually at "chine" but momentum carried me to the end of the word. On DDG you have to make the effort to estimate the marginal utility of further typing because you don't get the results until you submit the query. If you don't like the result the iteration cycle is slower on DDG.
