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