• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu tinh - canh tranh ((cua dung) OR (qua dung)) huong ((doan phan) OR (doanh phan)) cac*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu tinh - canh tranh ((cua dung) or (qua dung)) huong ((doan phan) OR (doanh phan)) cac*".
