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