• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu sach - thanh trung tuan nhung ((cong van) OR (cong san)) ((tan cau) or (tan ca))~".
• Adding a wildcard symbol may retrieve word variants: theo chu sach - thanh trung tuan nhung ((cong van) OR (cong san)) ((tan cau) or (tan ca))*.
