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