• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - thanh trung va ((nhung cong) OR (tong cong)) san ((than cap) OR (thanh cac))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - thanh trung va ((nhung cong) or (tong cong)) san ((than cap) OR (thanh cac))*".
