• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo dieu) OR (thuoc dieu)) hanh - anh hung ca nhung cong ((tan toan) OR (van toan)) cao~.
• Adding a wildcard symbol may retrieve word variants: ((theo dieu) or (thuoc dieu)) hanh - anh hung ca nhung cong ((tan toan) or (van toan)) cao*.
