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