• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong sin) OR (dong sink)) ya hua rents ((ying jin) OR ((yang OR wang) di)) cong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong sin) or (dong sink)) ya hua rents ((ying jin) or ((yang OR wang) di)) cong shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((dong sin) or (dong sink)) ya hua rents ((ying jin) or ((yang OR wang) di)) cong shu ;*.
