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

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