You can append !gvb to a DDG search to directly perform a Google verbatim search. It's the fastest way to do a Google verbatim search - faster than Google's own UI.
Not only does appending !gvb to a DDG search perform a Google verbatim search, it also directly reveals the Google UI for searching a date range.
The combination of normal DDG plus easy access to Google verbatim and date range seaches gives a pretty nice search experience.
