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