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