• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu sach - canh tranh quang phuong ((cong dan) OR (cong san)) ((toan tai) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu sach - canh tranh quang phuong ((cong dan) OR (cong san)) ((toan tai) or (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu sach - canh tranh quang phuong ((cong dan) OR (cong san)) ((toan tai) or (toan tap))*.
