• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu sach - ((thanh trang) OR (thanh trung)) ((van dung) OR (mat duong)) cong dan toan tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sach - ((thanh trang) OR (thanh trung)) ((van dung) or (mat duong)) cong dan toan tap".
• Adding a wildcard symbol may retrieve word variants: doi chieu sach - ((thanh trang) OR (thanh trung)) ((van dung) or (mat duong)) cong dan toan tap*.
