• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky ((mang xa) OR (((lang ha) OR (long ha)))) hoi. hieu van nam thuoc van anh ve cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky ((mang xa) or (((lang ha) OR (long ha)))) hoi. hieu van nam thuoc van anh ve cua te*".
