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