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