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