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