Perhaps you should try some spelling variations:
"history and matematica" » "history en matematica", "history en matematicas", "history la matematica"
"history in mathematics" » "history en matematicas", "history en matematica", "history of mathematics", "history a mathematics"
"history y matematicas" » "history de matematicas", "history en matematicas", "history las matematicas", "history a matematicas", "historia y matematicas", "history of matematicas"

You may be able to get more results by adjusting your search query.

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