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