Perhaps you should try some spelling variations:
workers volunteer » workers volunteers, others volunteer, words volunteer
worker volunteer » workers volunteers, words volunteer, brother volunteer
new workers » new yorker, new markers, line workers
new worker » new yorker, new work, new marker
infantry » infant, infants, infancy
regiment\" » regimen\", 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 volunteer infantry (regiment\" OR regimes\")) OR (\"7th new workers volunteer infantry (regiment\" OR regimes\")))".
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"7th new worker volunteer infantry (regiment\\" OR regimes\\")) or (\\"7th new workers volunteer infantry (regiment\\" OR regimes\\")))\"".
• Removing quotes may allow a broader search: (( 7th new worker volunteer infantry (regiment OR regimes )) or ( 7th new workers volunteer infantry (regiment OR regimes ))).
