• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"nhung mai luan van. boi nguong nguoi mo\") OR (\"phung thi qua van. boi duong nguoi co\"))*".
• Removing quotes may allow a broader search: (( nhung mai luan van. boi nguong nguoi mo ) OR ( phung thi qua van. boi duong nguoi co ))*.
