• The words AND, OR and NOT may confuse the search; try adding quotes: "(( 7th new ((mock volunteers) OR (local volunteers)) his regiment ) or ( 7th new mock volunteer it's regiment ))".
• Adding a wildcard symbol may retrieve word variants: (( 7th new ((mock volunteers) OR (local volunteers)) his regiment ) or ( 7th new mock volunteer it's regiment ))*.
