• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu sang)) - thanh trung qua dung ((cong van) OR (cong san)) thang cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu sang)) - thanh trung qua dung ((cong van) or (cong san)) thang cau*".
