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