• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu tinh - thanh trung ((((cua dung) OR (cua rung))) OR (cua dang)) cong dan thanh cac.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu tinh - thanh trung ((((cua dung) OR (cua rung))) or (cua dang)) cong dan thanh cac".
• Adding a wildcard symbol may retrieve word variants: theo chieu tinh - thanh trung ((((cua dung) OR (cua rung))) or (cua dang)) cong dan thanh cac*.
