• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ((thu hang) OR (thi hang)) ((ca hoi) or (xa hoi)). hieu ve chat thuc va dinh dai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((thu hang) OR (thi hang)) ((ca hoi) OR (xa hoi)). hieu ve chat thuc va dinh dai cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((thu hang) OR (thi hang)) ((ca hoi) or (xa hoi)). hieu ve chat thuc va dinh dai cua triet*".
