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