• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) OR (thu sach)) tham nang xa hoi. hieu ve ((cham xuc) or (cam xuc)) ban thanh di cau tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thu sach)) tham nang xa hoi. hieu ve ((cham xuc) OR (cam xuc)) ban thanh di cau tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (thu sach)) tham nang xa hoi. hieu ve ((cham xuc) or (cam xuc)) ban thanh di cau tren".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (thu sach)) tham nang xa hoi. hieu ve ((cham xuc) or (cam xuc)) ban thanh di cau tren*.
