chieu sach » chinh sach, chiet tach, chieu sang
hanh trinh » canh tranh, hanh chinh

• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((nhiet nang) OR (chieu sach)) - hanh trinh cua truong cong vang ((toan tap) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((nhiet nang) or (chieu sach)) - hanh trinh cua truong cong vang ((toan tap) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: theo ((nhiet nang) or (chieu sach)) - hanh trinh cua truong cong vang ((toan tap) OR (toan ban))*.
