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