• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu sach)) - ((thanh trung) OR (hanh trang)) va dung cong tac quan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu sach)) - ((thanh trung) or (hanh trang)) va dung cong tac quan cao".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu sach)) - ((thanh trung) or (hanh trang)) va dung cong tac quan cao*.
