• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((hoi dan) or (thi van)) - doanh doanh quan nhung ((cong danh) OR (cong dan)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((hoi dan) or (thi van)) - doanh doanh quan nhung ((cong danh) OR (cong dan)) toan cau*.
