• If you are trying to use Boolean operators, they must be ALL CAPS: o ((chau tinh) OR (ha tinh)) - thanh tra tuan trong cong tan ((toan cau) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "o ((chau tinh) or (ha tinh)) - thanh tra tuan trong cong tan ((toan cau) OR (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: o ((chau tinh) or (ha tinh)) - thanh tra tuan trong cong tan ((toan cau) OR (toan tap))*.
