• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu sach - thanh trung cua nhung tuong ((manh toan) OR (((dan chan) OR (dan gian)))) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu sach - thanh trung cua nhung tuong ((manh toan) or (((dan chan) OR (dan gian)))) cau~".
• Adding a wildcard symbol may retrieve word variants: theo chu sach - thanh trung cua nhung tuong ((manh toan) or (((dan chan) OR (dan gian)))) cau*.
