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