• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang liang) OR (yang yang)) taiwan china dan yang day ((line d) OR (line 3)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang liang) or (yang yang)) taiwan china dan yang day ((line d) OR (line 3)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang liang) or (yang yang)) taiwan china dan yang day ((line d) OR (line 3)) ;*.
