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: "((\"applying computation using computer program\") OR (\"using codes from python programming\"))~".
• Removing quotes may allow a broader search: (( applying computation using computer program ) OR ( using codes from python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("applying computation using computer program") OR ("using codes from python programming"))*.
