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