• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) OR (te sach)) ky nang ho hai. hieu ((van cau) or (van hac)) duc va thanh lam cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) ky nang ho hai. hieu ((van cau) OR (van hac)) duc va thanh lam cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (te sach)) ky nang ho hai. hieu ((van cau) or (van hac)) duc va thanh lam cua triet".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (te sach)) ky nang ho hai. hieu ((van cau) or (van hac)) duc va thanh lam cua triet*.
