• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) OR (so sach)) ky sang tai hai. hieu ve cac xuc ((va dan) or (va dinh)) vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sach)) ky sang tai hai. hieu ve cac xuc ((va dan) OR (va dinh)) vi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (so sach)) ky sang tai hai. hieu ve cac xuc ((va dan) or (va dinh)) vi cua te*".
