• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"historicas materiales\") OR (\"historicol materiales\"))) OR (\"historica materialism\"))~".
• Removing quotes may allow a broader search: (((( historicas materiales ) OR ( historicol materiales ))) OR ( historica materialism ))~.
• Adding a wildcard symbol may retrieve word variants: (((("historicas materiales") OR ("historicol materiales"))) OR ("historica materialism"))*.
