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