• Removing quotes may allow a broader search: (( history of mathematics ) OR ((( historia con mathematica ) OR ( historia rural matematicas ))))~.
• Adding a wildcard symbol may retrieve word variants: (("history of mathematics") OR ((("historia con mathematica") OR ("historia rural matematicas"))))*.
