• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (su sach)) ky tang hoa hoi. hieu ve nam thuc va thanh dieu ((cua tre) OR (cuu tre))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (su sach)) ky tang hoa hoi. hieu ve nam thuc va thanh dieu ((cua tre) OR (cuu tre))~".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (su sach)) ky tang hoa hoi. hieu ve nam thuc va thanh dieu ((cua tre) OR (cuu tre))*.
