Talvez debería tentar con algunhas variantes ortográficas:
communication channel » communication channels, communication case, communication challenges
component dimensions » competency dimensions, complex dimensions, content dimensions
channel component » change components, annex component, tunnel component
shared spaces » shared space, shared stocks
tuple spaces » tuple space, triple space
type spaces » state 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 channel component dimensions ((((tuple spaces) or (type spaces))) or (shared spaces))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication channel component dimensions ((((tuple spaces) OR (type spaces))) OR (shared spaces)).
• Adding a wildcard symbol may retrieve word variants: communication channel component dimensions ((((tuple spaces) or (type spaces))) or (shared spaces))*.
