• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - canh tranh ((cua bang) OR (chua bang)) ((cong tinh) OR (cong vinh)) toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - canh tranh ((cua bang) or (chua bang)) ((cong tinh) OR (cong vinh)) toan cao~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - canh tranh ((cua bang) or (chua bang)) ((cong tinh) OR (cong vinh)) toan cao*.
