• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty nang ((x hoi) OR (o hoi)). hieu ve ((chat duc) OR (chat xuc)) van anh lai cua viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty nang ((x hoi) OR (o hoi)). hieu ve ((chat duc) or (chat xuc)) van anh lai cua viet".
