• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - thanh trung cua dang ((cong van) OR (cong san)) ((than cap) OR (thanh lap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - thanh trung cua dang ((cong van) or (cong san)) ((than cap) OR (thanh lap))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - thanh trung cua dang ((cong van) or (cong san)) ((than cap) OR (thanh lap))*.
