• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"and computation in sio2 program\") OR (\"using python python python programming\"))~".
• Removing quotes may allow a broader search: (( and computation in sio2 program ) OR ( using python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("and computation in sio2 program") OR ("using python python python programming"))*.
