Talvez debería tentar con algunhas variantes ortográficas:
communication controller » communication controllers, communication controlling, communication control
controller content » controller concept, controls content, controller internet
content dimensions » concept dimensions, constant dimension, current dimensions
tuple spaces » type spaces, triple space
tuple space » people space
use spaces » phase spaces, gauge spaces, whose spaces

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

• Performing a fuzzy search may retrieve terms with similar spellings: communication controller content dimensions ((((tuple spaces) or (tuple space))) or (use spaces))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication controller content dimensions ((((tuple spaces) OR (tuple space))) OR (use spaces)).
• Adding a wildcard symbol may retrieve word variants: communication controller content dimensions ((((tuple spaces) or (tuple space))) or (use spaces))*.
