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