• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"critical rationalism\") OR (\"critical racionalismo\"))) OR (\"criticas rationality\"))".
• Removing quotes may allow a broader search: (((( critical rationalism ) OR ( critical racionalismo ))) OR ( criticas rationality )).
• Adding a wildcard symbol may retrieve word variants: (((("critical rationalism") OR ("critical racionalismo"))) OR ("criticas rationality"))*.
