Perhaps you should try some spelling variations:
single domains » finite domains, single chains
synfire chain » synfire chains, entire chain, synfue chains
single domain » single chain
singie chain » single chain, single chains, side chain

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((((\\"synfire chain\\") or (\\"singie chain\\"))) or (((\\"single channel\\") or (\\"((single domains) OR (single domain))\\"))))\"".
• Removing quotes may allow a broader search: (((( synfire chain ) or ( singie chain ))) or ((( single channel ) or ( ((single domains) OR (single domain)) )))).
