• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (doi chieu)) sang - manh trung cua bang cong van ((thang cau) OR (thong cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (doi chieu)) sang - manh trung cua bang cong van ((thang cau) OR (thong cau))~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (doi chieu)) sang - manh trung cua bang cong van ((thang cau) OR (thong cau))*.
