• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) OR (te sach)) y lang van hoa. thien van cam cuc ban ((hang va) or (hang di)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) y lang van hoa. thien van cam cuc ban ((hang va) OR (hang di)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (te sach)) y lang van hoa. thien van cam cuc ban ((hang va) or (hang di)) cua triet".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (te sach)) y lang van hoa. thien van cam cuc ban ((hang va) or (hang di)) cua triet*.
