• If you are trying to use Boolean operators, they must be ALL CAPS: su sach thu dang ((((ha hoi) OR (va hoi))) OR (hoa hoi)). hieu ve cac xuc va thanh viec cua cu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach thu dang ((((ha hoi) OR (va hoi))) or (hoa hoi)). hieu ve cac xuc va thanh viec cua cu".
