• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - tinh toan ((tuan bang) OR (tuan hoang)) ((cong van) or (cong san)) nhanh ha~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - tinh toan ((tuan bang) OR (tuan hoang)) ((cong van) or (cong san)) nhanh ha*.
