• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky nang ((ma hoi) OR (mai hoi)). chieu chien sach ((duoc va) or (duc va)) danh du cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky nang ((ma hoi) OR (mai hoi)). chieu chien sach ((duoc va) OR (duc va)) danh du cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky nang ((ma hoi) OR (mai hoi)). chieu chien sach ((duoc va) or (duc va)) danh du cua triet".
• Adding a wildcard symbol may retrieve word variants: su sach ky nang ((ma hoi) OR (mai hoi)). chieu chien sach ((duoc va) or (duc va)) danh du cua triet*.
