Perhaps you should try some spelling variations:
"chicago fire s.c." » "chicago die s.c.", "chicago circle s.c.", "chicago price s.c.", "chicago fire 2.5.", "chicago site s.c.", "chicago fire 1.2."
"chicago pile s.c." » "chicago price s.c.", "chicago il s.c.", "chicago ill s.c.", "chicago site s.c.", "chicago pile 3.2.", "chicago pile 5.1."

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: (("chicago fire s.c.") OR ("chicago pile s.c.")).
• Removing quotes may allow a broader search: (( chicago fire s.c. ) or ( chicago pile s.c. )).
• Adding a wildcard symbol may retrieve word variants: (("chicago fire s.c.") or ("chicago pile s.c."))*.
