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