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