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