Perhaps you should try some spelling variations:
communication control » communication concepts, communication culture, communication channel
course dimensions » core dimensions, four dimensions, course divisions
control course » control coupled, control case, control costs
larger spaces » larger species, large space, larger scale
range spaces » range states, large spaces, tangent spaces
gauge spaces » large space, safe spaces, use spaces

• If you are trying to use Boolean operators, they must be ALL CAPS: communication control course dimensions ((((range spaces) OR (gauge spaces))) OR (larger spaces)).
• Adding a wildcard symbol may retrieve word variants: communication control course dimensions ((((range spaces) or (gauge spaces))) or (larger spaces))*.
