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