• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (doi chieu)) sang - ((nhanh thang) OR (hanh phan)) va tong cong manh toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (doi chieu)) sang - ((nhanh thang) or (hanh phan)) va tong cong manh toan cau*".
