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

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