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