• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder coder proof complexity problem\") OR (\"manim python python python programming\"))*".
• Removing quotes may allow a broader search: (( coder coder proof complexity problem ) OR ( manim python python python programming ))*.
