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