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