Perhaps you should try some spelling variations:
communicative context » communication contexts, communication content, communication control
units dimensions » finite dimensions, its dimension, rims dimensions
context units » contexts suniti, content united, context ednita
state dspaces » state spaces, state space, tate spaces
type dspaces » type spaces, type spares
dspaces » ddspaces
space » dspace

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: communicative context units dimensions ((((type dspaces) OR (shape space))) OR (state dspaces))~.
• Adding a wildcard symbol may retrieve word variants: communicative context units dimensions ((((type dspaces) or (shape space))) or (state dspaces))*.
