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

• Performing a fuzzy search may retrieve terms with similar spellings: (("using functionals dft computation code") OR ("using coding python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"using functionals dft computation code\") OR (\"using coding python python programming\"))".
• Removing quotes may allow a broader search: (( using functionals dft computation code ) OR ( using coding python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("using functionals dft computation code") OR ("using coding python python programming"))*.
