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