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