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