• If you are trying to use Boolean operators, they must be ALL CAPS: tu xach tay lang ha hoi. ((hieu ke) OR (hieu kem)) ((cau hoc) OR (cao hoc)) va hang di cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu xach tay lang ha hoi. ((hieu ke) OR (hieu kem)) ((cau hoc) or (cao hoc)) va hang di cua te~".
• Adding a wildcard symbol may retrieve word variants: tu xach tay lang ha hoi. ((hieu ke) OR (hieu kem)) ((cau hoc) or (cao hoc)) va hang di cua te*.
