• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu xanh - ((hanh dung) OR (thanh dung)) cua ((khong cong) OR (thong cong)) van toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu xanh - ((hanh dung) OR (thanh dung)) cua ((khong cong) or (thong cong)) van toan cao".
• Adding a wildcard symbol may retrieve word variants: theo chieu xanh - ((hanh dung) OR (thanh dung)) cua ((khong cong) or (thong cong)) van toan cao*.
