• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu sach - thanh thuong ((va hang) OR (va lang)) ((luong manh) OR (duong manh)) toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu sach - thanh thuong ((va hang) OR (va lang)) ((luong manh) or (duong manh)) toan cau".
• Adding a wildcard symbol may retrieve word variants: hoc thieu sach - thanh thuong ((va hang) OR (va lang)) ((luong manh) or (duong manh)) toan cau*.
