• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (doc hieu)) xanh - thanh dong va nhung dong van ((ban cau) OR (ban can))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (doc hieu)) xanh - thanh dong va nhung dong van ((ban cau) OR (ban can))*".
