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