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