• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu sach - thanh luong ((quan duong) OR (quan dong)) song van ((tuan cau) OR (toan cau))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu sach - thanh luong ((quan duong) OR (quan dong)) song van ((tuan cau) or (toan cau))*".
