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