• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu sach - canh tranh va ((((nhung chong) OR (nhung cong))) OR (phong cong)) van chat cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sach - canh tranh va ((((nhung chong) OR (nhung cong))) or (phong cong)) van chat cau*".
