Perhaps you should try some spelling variations:
communication objects » communication object, communicating objects, communication aspects
methods dimension » methods diffusion, ethics dimension, metholodgy dimension
objects methods » objectives methods, objective methods, projects methods
sample spaces » sample space, sample speeches, sample sizes
whose spaces » phase spaces, shape spaces, whose race
state spaces » state space

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 objects methods dimension ((((whose spaces) OR (sample spaces))) OR (state spaces))~.
• Adding a wildcard symbol may retrieve word variants: communication objects methods dimension ((((whose spaces) or (sample spaces))) or (state spaces))*.
