• If you are trying to use Boolean operators, they must be ALL CAPS: ho chiet tach - thanh trung cua nhung ((cong dan) OR (huong dan)) ((than cau) OR (phan dau))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chiet tach - thanh trung cua nhung ((cong dan) OR (huong dan)) ((than cau) or (phan dau))*".
