• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chieu sang) OR (chieu sach)) - ((thanh dung) OR (thanh hung)) cuc phuong thong den toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu sang) OR (chieu sach)) - ((thanh dung) or (thanh hung)) cuc phuong thong den toan cao~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu sang) OR (chieu sach)) - ((thanh dung) or (thanh hung)) cuc phuong thong den toan cao*.
