• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty sang tao boi. ((hieu ve) OR (hieu van)) cham luc ban hang lap ((cua tre) OR (cua te))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty sang tao boi. ((hieu ve) OR (hieu van)) cham luc ban hang lap ((cua tre) or (cua te))~".
• Adding a wildcard symbol may retrieve word variants: tu sach ty sang tao boi. ((hieu ve) OR (hieu van)) cham luc ban hang lap ((cua tre) or (cua te))*.
