Perhaps you should try some spelling variations:
things during » things using, things sharing, thing hiring
last things » last thing, first things, smart things
sudan died » sudan die, sudan der
died last » die last, der last
lang yan » wang yang, zhang yan, yang yang
dong hoi » wong hoi, jong ho, dong di

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((lang yan) OR (wang yan)) sudan died last things during ((dong sin) OR (dong hoi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((lang yan) OR (wang yan)) sudan died last things during ((dong sin) or (dong hoi)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((lang yan) OR (wang yan)) sudan died last things during ((dong sin) or (dong hoi)) ;*.
