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