• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu xanh - canh ((tranh va) OR (trinh quan)) ((nhung duong) OR (nhung dung)) van than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu xanh - canh ((tranh va) or (trinh quan)) ((nhung duong) OR (nhung dung)) van than cau".
