• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder detection by coding program\") OR (\"coverage estimation python python programming\"))*".
• Removing quotes may allow a broader search: (( coder detection by coding program ) OR ( coverage estimation python python programming ))*.
