• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"using computation and computing programming\") OR (\"using code form python programming\"))".
• Removing quotes may allow a broader search: (( using computation and computing programming ) OR ( using code form python programming )).
• Adding a wildcard symbol may retrieve word variants: (("using computation and computing programming") OR ("using code form python programming"))*.
