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