• Removing quotes may allow a broader search: (( historico in mathematics ) OR ((( historia del mathematics ) OR ( historia las matematicas ))))~.
• Adding a wildcard symbol may retrieve word variants: (("historico in mathematics") OR ((("historia del mathematics") OR ("historia las matematicas"))))*.
