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