• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu sang - manh ((trung tuan) OR (truong cua)) khong cong ((anh toan) OR (manh toan)) cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu sang - manh ((trung tuan) or (truong cua)) khong cong ((anh toan) OR (manh toan)) cau".
