• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder coding coding frequency coupling\") OR (\"in python python python programming\"))*".
• Removing quotes may allow a broader search: (( coder coding coding frequency coupling ) OR ( in python python python programming ))*.
