• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y hoang van hoi. hieu ((va nhan) OR (va phan)) ((duc va) OR (tuc va)) hang dien cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y hoang van hoi. hieu ((va nhan) OR (va phan)) ((duc va) or (tuc va)) hang dien cuu tre".
