• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"sale / taxation / germany / prussia\") OR (\"sale / taxation / germany / russia\"))".
• Removing quotes may allow a broader search: (( sale / taxation / germany / prussia ) OR ( sale / taxation / germany / russia )).
• Adding a wildcard symbol may retrieve word variants: (("sale / taxation / germany / prussia") OR ("sale / taxation / germany / russia"))*.
