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