Talvez debería tentar con algunhas variantes ortográficas:
communication controller » communication controllers, communication controlling, communication control
controller current » control current, control recurrent, contractor current
current dimensions » current directions, current diversion, content dimensions
tuple spaces » type spaces, triple space
whose spaces » phase spaces, shape spaces, whose race
tuple space » people space

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 current dimensions ((((tuple spaces) or (tuple space))) or (whose spaces))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication controller current dimensions ((((tuple spaces) OR (tuple space))) OR (whose spaces)).
• Adding a wildcard symbol may retrieve word variants: communication controller current dimensions ((((tuple spaces) or (tuple space))) or (whose spaces))*.
