• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu sang - manh ((hung ca) OR (nhung ca)) hang cong danh ((toan cao) OR (toan ban)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sang - manh ((hung ca) OR (nhung ca)) hang cong danh ((toan cao) or (toan ban))".
• Adding a wildcard symbol may retrieve word variants: theo chieu sang - manh ((hung ca) OR (nhung ca)) hang cong danh ((toan cao) or (toan ban))*.
