Perhaps you should try some spelling variations:
"synfire chain" » "synfire chains", "singie chain", "synfue chains"
"single chains" » "single chain", "single channel", "single domains"
"entire chain" » "entire brain", "entire domain", "entire change"
"single chip" » "single chain"

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: (((((("synfire chain") OR ("entire chain"))) OR ("single chip"))) OR ("single chains")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"synfire chain\") OR (\"entire chain\"))) or (\"single chip\"))) or (\"single chains\"))".
• Removing quotes may allow a broader search: (((((( synfire chain ) OR ( entire chain ))) or ( single chip ))) or ( single chains )).
• Adding a wildcard symbol may retrieve word variants: (((((("synfire chain") OR ("entire chain"))) or ("single chip"))) or ("single chains"))*.
