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