• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) or (vu sach)) ly nang ma hoi. ((hieu van) OR (thien van)) am thuc va dinh hai cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu sach)) ly nang ma hoi. ((hieu van) OR (thien van)) am thuc va dinh hai cau treo*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (vu sach)) ly nang ma hoi. ((hieu van) OR (thien van)) am thuc va dinh hai cau treo*".
