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