• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"german colonialism empire\") OR (\"german colonialism emerges\"))) or (\"german colonial empires\"))".
• Removing quotes may allow a broader search: (((( german colonialism empire ) OR ( german colonialism emerges ))) or ( german colonial empires )).
• Adding a wildcard symbol may retrieve word variants: (((("german colonialism empire") OR ("german colonialism emerges"))) or ("german colonial empires"))*.
