• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ky mang) OR (ke mang)) tay o. hieu ve cham duc ((va gianh) OR (va gian)) thai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ky mang) or (ke mang)) tay o. hieu ve cham duc ((va gianh) OR (va gian)) thai cua te*".
