• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (theo chieu)) tinh - ((hanh mang) OR (nhanh mang)) luan nhung cong van phan tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (theo chieu)) tinh - ((hanh mang) or (nhanh mang)) luan nhung cong van phan tap*".
