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