You may be able to get more results by adjusting your search query.

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