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