• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) OR (te sach)) ky danh van hoi. hieu ve cam xuc ((va thanh) or (may tinh)) van luc tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) ky danh van hoi. hieu ve cam xuc ((va thanh) OR (may tinh)) van luc tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (te sach)) ky danh van hoi. hieu ve cam xuc ((va thanh) or (may tinh)) van luc tre".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (te sach)) ky danh van hoi. hieu ve cam xuc ((va thanh) or (may tinh)) van luc tre*.
