• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu tinh)) - thanh tung quang dung cong ((tan toan) OR (tan tran)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu tinh)) - thanh tung quang dung cong ((tan toan) OR (tan tran)) cau*".
