• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu sach) OR (hieu cach)) - manh truong cua nhung chong van ((toan tap) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu sach) or (hieu cach)) - manh truong cua nhung chong van ((toan tap) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu sach) or (hieu cach)) - manh truong cua nhung chong van ((toan tap) OR (toan ban))*.
