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