• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (doi chieu)) tinh - manh ((trung dai) OR (trung tam)) cuong cong ban than cap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (doi chieu)) tinh - manh ((trung dai) or (trung tam)) cuong cong ban than cap".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (doi chieu)) tinh - manh ((trung dai) or (trung tam)) cuong cong ban than cap*.
