• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chinh sach) OR (((chieu sang) OR (chieu xanh)))) - thanh trung va nhung cong dan toan cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chinh sach) or (((chieu sang) OR (chieu xanh)))) - thanh trung va nhung cong dan toan cao*".
