• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chinh sach) OR (((chiet tach) OR (chieu sach)))) - canh doanh luan dang cong dan toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chinh sach) or (((chiet tach) OR (chieu sach)))) - canh doanh luan dang cong dan toan ban~".
• Adding a wildcard symbol may retrieve word variants: ho ((chinh sach) or (((chiet tach) OR (chieu sach)))) - canh doanh luan dang cong dan toan ban*.
