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