• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - thanh trung cua khong cong ((((dan toan) OR (manh toan))) OR (van than)) cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - thanh trung cua khong cong ((((dan toan) OR (manh toan))) or (van than)) cau".
