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