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