• If you are trying to use Boolean operators, they must be ALL CAPS: te sach tai ((((nuoc sach) OR (cuon sach))) OR (hoc sach)) khoa ((phau thong) OR (phan hong))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach tai ((((nuoc sach) OR (cuon sach))) or (hoc sach)) khoa ((phau thong) or (phan hong))*".
