• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu sang) OR (chieu sach)) - thanh truong a ((chong cong) OR (cuong cong)) tan tran cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu sang) or (chieu sach)) - thanh truong a ((chong cong) OR (cuong cong)) tan tran cau".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu sang) or (chieu sach)) - thanh truong a ((chong cong) OR (cuong cong)) tan tran cau*.
