• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cach tay lang ((ha hoi) OR (ha noi)). ((hieu ke) OR (chieu ke)) cau hoc va hang di cua te~".
• Adding a wildcard symbol may retrieve word variants: tu cach tay lang ((ha hoi) OR (ha noi)). ((hieu ke) OR (chieu ke)) cau hoc va hang di cua te*.
