• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"using computational using computer program\") OR (\"using coding model python programming\"))*".
• Removing quotes may allow a broader search: (( using computational using computer program ) OR ( using coding model python programming ))*.
