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