Perhaps you should try some spelling variations:
communication controls » communication control, communications control, communication controllers
client dimensions » content dimensions, current dimensions, china dimensions
controls client » controls content, controls saint, controls plant
state spaces » state space
whose spaces » phase spaces, shape spaces, whose race
use spaces » tuple spaces, phase spaces, gauge 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 controls client dimensions ((state spaces) OR (((use spaces) OR (whose spaces))))~.
• Adding a wildcard symbol may retrieve word variants: communication controls client dimensions ((state spaces) or (((use spaces) or (whose spaces))))*.
