• If you are trying to use Boolean operators, they must be ALL CAPS: (((( ((canh tay) OR (ban tay)) van toan thien nam ) OR ((( anh ta van hoa phien nam ) OR ( anh tap van hoa hien nay ))))) OR ((((( canh uy ban toan trien nhan ) OR ( canh tui ban toan trien nhan ))) OR ( canh tao ((ban than) OR (ban hang)) vien nam ))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( ((canh tay) OR (ban tay)) van toan thien nam ) or ((( anh ta van hoa phien nam ) or ( anh tap van hoa hien nay ))))) or ((((( canh uy ban toan trien nhan ) or ( canh tui ban toan trien nhan ))) or ( canh tao ((ban than) or (ban hang)) vien nam ))))~".
• Adding a wildcard symbol may retrieve word variants: (((( ((canh tay) OR (ban tay)) van toan thien nam ) or ((( anh ta van hoa phien nam ) or ( anh tap van hoa hien nay ))))) or ((((( canh uy ban toan trien nhan ) or ( canh tui ban toan trien nhan ))) or ( canh tao ((ban than) or (ban hang)) vien nam ))))*.
