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