• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"historia in mathematical\") OR (\"historia del matematica\"))) OR (\"historia las matematicas\"))".
• Removing quotes may allow a broader search: (((( historia in mathematical ) OR ( historia del matematica ))) OR ( historia las matematicas )).
• Adding a wildcard symbol may retrieve word variants: (((("historia in mathematical") OR ("historia del matematica"))) OR ("historia las matematicas"))*.
