Perhaps you should try some spelling variations:
worker volunteer » workers volunteers, words volunteer, brother volunteer
its regiment » his regiment, 9th regiment, ist regiment
das regiment » a regiment, his regiment, das regime
new worker » new workers, new yorker, new work

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "7th new worker volunteer ((its regiment) OR (das regiment))".
• Adding a wildcard symbol may retrieve word variants: 7th new worker volunteer ((its regiment) OR (das regiment))*.
