• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - thanh tung cua ((((thong cong) OR (phong chong))) OR (tong cong)) van than cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - thanh tung cua ((((thong cong) OR (phong chong))) or (tong cong)) van than cau*".
