• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu sach - canh tranh ((cua khong) OR (((phuc khong) OR (chu khong)))) cong dan than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sach - canh tranh ((cua khong) or (((phuc khong) OR (chu khong)))) cong dan than cau".
• Adding a wildcard symbol may retrieve word variants: theo chieu sach - canh tranh ((cua khong) or (((phuc khong) OR (chu khong)))) cong dan than cau*.
