Perhaps you should try some spelling variations:
communication concepts » communication circuits, communication congresses, communication channels
more dimensions » core dimensions, moral dimensions, some dimensions
concepts more » concepts sore, concepts model, concepts mike
sample spaces » sample space, sample speeches, sample sizes
shared spaces » shared space, shared stocks
type spaces » state 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: communication concepts more dimensions ((((sample spaces) OR (shared spaces))) OR (type spaces))~.
• Adding a wildcard symbol may retrieve word variants: communication concepts more dimensions ((((sample spaces) or (shared spaces))) or (type spaces))*.
