• If you are trying to use Boolean operators, they must be ALL CAPS: cho ((chuc danh) OR (chieu sach)) - hanh trung va nhung ((cong dan) OR (cong san)) toan tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cho ((chuc danh) or (chieu sach)) - hanh trung va nhung ((cong dan) OR (cong san)) toan tap".
• Adding a wildcard symbol may retrieve word variants: cho ((chuc danh) or (chieu sach)) - hanh trung va nhung ((cong dan) OR (cong san)) toan tap*.
