Talvez debería tentar con algunhas variantes ortográficas:
communications coding » communications using, communications banking, communications bringing
methods diffusion » networks diffusion, methods decision
coding methods » cooking methods, cooling methods, recording methods
shared spaces » shared space, shared stocks
tuple spaces » tuple space, type spaces, triple space
life spaces » life space, life stages, safe spaces

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

• If you are trying to use Boolean operators, they must be ALL CAPS: communications coding methods diffusion ((((tuple spaces) OR (life spaces))) OR (shared spaces))~.
• Adding a wildcard symbol may retrieve word variants: communications coding methods diffusion ((((tuple spaces) or (life spaces))) or (shared spaces))*.
