• Performing a fuzzy search may retrieve terms with similar spellings: (((("history a matematico") OR ("historia del matematico"))) OR ("history e matematica"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"history a matematico\") OR (\"historia del matematico\"))) OR (\"history e matematica\"))".
• Removing quotes may allow a broader search: (((( history a matematico ) OR ( historia del matematico ))) OR ( history e matematica )).
• Adding a wildcard symbol may retrieve word variants: (((("history a matematico") OR ("historia del matematico"))) OR ("history e matematica"))*.
