• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu sang) OR (chieu sach)) - manh ((tran tuan) OR (tran xuan)) chung cuong danh toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu sang) or (chieu sach)) - manh ((tran tuan) OR (tran xuan)) chung cuong danh toan cao".
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu sang) or (chieu sach)) - manh ((tran tuan) OR (tran xuan)) chung cuong danh toan cao*.
