• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((hieu manh) or (hieu lang)) - hanh chinh quan hang ((cong van) OR (cong san)) thanh cap~".
• Adding a wildcard symbol may retrieve word variants: ho ((hieu manh) or (hieu lang)) - hanh chinh quan hang ((cong van) OR (cong san)) thanh cap*.
