• Performing a fuzzy search may retrieve terms with similar spellings: hoc hien sach - thanh trung luan phuong ((((cang dan) OR (canh dan))) or (cong dan)) chan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hien sach - thanh trung luan phuong ((((cang dan) OR (canh dan))) OR (cong dan)) chan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien sach - thanh trung luan phuong ((((cang dan) OR (canh dan))) or (cong dan)) chan cau*".
