Perhaps you should try some spelling variations:
"synfire chain" » "entire chain", "synfue chains"
"synfire chains" » "entire chains", "synfue chainss"
"singie chain" » "single chain", "single chains", "ising chain"
"single chip" » "single chain"
"side chain" » "side 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 ("singie chain"))) OR ("synfire chains"))) OR ((("single chip") OR ("side chain")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"synfire chain\") OR (\"singie chain\"))) or (\"synfire chains\"))) or (((\"single chip\") or (\"side chain\"))))".
• Removing quotes may allow a broader search: (((((( synfire chain ) OR ( singie chain ))) or ( synfire chains ))) or ((( single chip ) or ( side chain )))).
• Adding a wildcard symbol may retrieve word variants: (((((("synfire chain") OR ("singie chain"))) or ("synfire chains"))) or ((("single chip") or ("side chain"))))*.
