• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu tinh) or (trieu tinh)) - chinh doanh cua nhung cong ((tac phan) OR (tai phan)) cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu tinh) or (trieu tinh)) - chinh doanh cua nhung cong ((tac phan) OR (tai phan)) cau*.
