• If you are trying to use Boolean operators, they must be ALL CAPS: ((mot chieu) OR (doi chieu)) sach - hoang vinh ((cua thuong) OR (cua phuong)) cong van toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((mot chieu) or (doi chieu)) sach - hoang vinh ((cua thuong) OR (cua phuong)) cong van toan cao~".
• Adding a wildcard symbol may retrieve word variants: ((mot chieu) or (doi chieu)) sach - hoang vinh ((cua thuong) OR (cua phuong)) cong van toan cao*.
