• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chieu) OR (cao chat)) xanh - hanh mang ((va dung) OR (va duong)) cong van tuan tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) or (cao chat)) xanh - hanh mang ((va dung) OR (va duong)) cong van tuan tap".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) or (cao chat)) xanh - hanh mang ((va dung) OR (va duong)) cong van tuan tap*.
