Perhaps you should try some spelling variations:
others volunteer » brother volunteer, her volunteer, workers volunteers
new worker » new workers, new work, new marker
new yorker » new york, new york's
new others » new mothers, few others, new other
infantry » infant, infants, infancy
regiment » regimen, regimes, regime

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

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