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