Perhaps you should try some spelling variations:

"history en matematica" » "history la matematica", "history el matematico", "history de matematica", "history and matematica", "history of matematica", "history a matematica"
"historia y matematica" » "historia y matematicas", "historia y matematico", "historia la matematica", "historia de matematica"

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