• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"history a mathematics\") OR (((\"history la matematicas\") OR (\"history las matematicas\"))))~".
• Removing quotes may allow a broader search: (( history a mathematics ) OR ((( history la matematicas ) OR ( history las matematicas ))))~.
• Adding a wildcard symbol may retrieve word variants: (("history a mathematics") OR ((("history la matematicas") OR ("history las matematicas"))))*.
