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