• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((y lang) OR (o lang)) xa hoi. hieu ve cham tuc va ((dinh toai) OR (hinh tai)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((y lang) OR (o lang)) xa hoi. hieu ve cham tuc va ((dinh toai) or (hinh tai)) cua tre*".
