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