• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((thi van) or (thi lan)) - hanh tranh cua nhung cong dan ((toan cao) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: theo ((thi van) or (thi lan)) - hanh tranh cua nhung cong dan ((toan cao) OR (toan ban))*.
