• If you are trying to use Boolean operators, they must be ALL CAPS: 7th new forms volunteer ((its regiment) OR (((his regiment) OR (_ regiment)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "7th new forms volunteer ((its regiment) or (((his regiment) OR (_ regiment))))".
• Adding a wildcard symbol may retrieve word variants: 7th new forms volunteer ((its regiment) or (((his regiment) OR (_ regiment))))*.
