• If you are trying to use Boolean operators, they must be ALL CAPS: ((nho hieu) OR (hoi phieu)) lang - hanh trinh cua dang cong ((dan toan) OR (tap toan)) cao~.
• Adding a wildcard symbol may retrieve word variants: ((nho hieu) or (hoi phieu)) lang - hanh trinh cua dang cong ((dan toan) or (tap toan)) cao*.
