Talvez debería tentar con algunhas variantes ortográficas:
communication collection » communication collections, communication connection, communication collective
methods dimension » methods diffusion, ethics dimension, metholodgy dimension
shared spaces » shared space, shared stocks
type spaces » state spaces
use spaces » tuple spaces, phase spaces, gauge 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 collection methods dimension ((((use spaces) or (shared spaces))) or (type spaces))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication collection methods dimension ((((use spaces) OR (shared spaces))) OR (type spaces)).
• Adding a wildcard symbol may retrieve word variants: communication collection methods dimension ((((use spaces) or (shared spaces))) or (type spaces))*.
