• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach thu xang ((((mai hoi) OR (lai hoi))) OR (ma hoa)). hieu van cham duc ban thanh lai su hien*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach thu xang ((((mai hoi) OR (lai hoi))) or (ma hoa)). hieu van cham duc ban thanh lai su hien*".
