• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - hanh tranh cua nhung cong ((((dan toan) OR (van toan))) OR (van tan)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - hanh tranh cua nhung cong ((((dan toan) OR (van toan))) or (van tan)) cau*".
