Talvez debería tentar con algunhas variantes ortográficas:
communication controls » communication control, communications control, communication controllers
current dimensions » current directions, current diversion, content dimensions
controls current » control current, control recurrent, controls client
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 controls current dimensions ((((tuple spaces) or (tuple space))) or (use spaces))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication controls current dimensions ((((tuple spaces) OR (tuple space))) OR (use spaces)).
• Adding a wildcard symbol may retrieve word variants: communication controls current dimensions ((((tuple spaces) or (tuple space))) or (use spaces))*.
