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