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