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