• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y ((dung tay) OR (dan tay)) hoi. hieu ve ((cam duc) OR (cam xuc)) ban anh dai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((dung tay) or (dan tay)) hoi. hieu ve ((cam duc) OR (cam xuc)) ban anh dai cua triet".
• Adding a wildcard symbol may retrieve word variants: te sach y ((dung tay) or (dan tay)) hoi. hieu ve ((cam duc) OR (cam xuc)) ban anh dai cua triet*.
