• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chinh sach) OR (chiet tach)) - thanh ((trung va) OR (trung ha)) nhung tuong ban than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chinh sach) or (chiet tach)) - thanh ((trung va) OR (trung ha)) nhung tuong ban than cau".
• Adding a wildcard symbol may retrieve word variants: theo ((chinh sach) or (chiet tach)) - thanh ((trung va) OR (trung ha)) nhung tuong ban than cau*.
