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