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