• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach y nang ((ma hoi) OR (ma hoa)). lieu ((va nham) OR (va tham)) thuc xa xanh doi cua su.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach y nang ((ma hoi) or (ma hoa)). lieu ((va nham) OR (va tham)) thuc xa xanh doi cua su".
