• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"historico por mathematics\") OR (((\"historia la matematicas\") OR (\"historia de matematica\"))))~".
• Removing quotes may allow a broader search: (( historico por mathematics ) OR ((( historia la matematicas ) OR ( historia de matematica ))))~.
• Adding a wildcard symbol may retrieve word variants: (("historico por mathematics") OR ((("historia la matematicas") OR ("historia de matematica"))))*.
