• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (te sach)) ky dang xa hoi. hieu va nhan duc va thanh loi ((cua tre) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (te sach)) ky dang xa hoi. hieu va nhan duc va thanh loi ((cua tre) OR (cua te))*".
