• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky ((dang mam) OR (dang mau)) hoi. hieu ve cham luc va van tai ((cuc tre) OR (duc tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky ((dang mam) OR (dang mau)) hoi. hieu ve cham luc va van tai ((cuc tre) or (duc tre))*".
