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