Perhaps you should try some spelling variations:
"history and matematica" » "history en matematica", "history en matematicas", "history la matematica"
"history lda matematica" » "history la matematica", "history da matematica", "history la matematicas", "history a matematica"
"history de matematica" » "history de matematicas", "history la matematica", "history en matematica", "historia de matematica", "history of matematica", "history a matematica"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("history lda matematica") OR ("history de matematica"))) OR ("history and matematica"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"history lda matematica\") OR (\"history de matematica\"))) OR (\"history and matematica\"))".
• Removing quotes may allow a broader search: (((( history lda matematica ) OR ( history de matematica ))) OR ( history and matematica )).
• Adding a wildcard symbol may retrieve word variants: (((("history lda matematica") OR ("history de matematica"))) OR ("history and matematica"))*.
