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