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