• If you are trying to use Boolean operators, they must be ALL CAPS: doanh chien thanh - canh tranh ((he nhung) OR (hee nhung)) cong manh ((toan cao) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doanh chien thanh - canh tranh ((he nhung) or (hee nhung)) cong manh ((toan cao) OR (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: doanh chien thanh - canh tranh ((he nhung) or (hee nhung)) cong manh ((toan cao) OR (toan tap))*.
