• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (su sach)) ty ((lang xa) OR (dang xay)) hoi. hieu ve cam tuc ban hang le cua vat~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (su sach)) ty ((lang xa) or (dang xay)) hoi. hieu ve cam tuc ban hang le cua vat~".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (su sach)) ty ((lang xa) or (dang xay)) hoi. hieu ve cam tuc ban hang le cua vat*.
