Talvez debería tentar con algunhas variantes ortográficas:
communication control » communication concepts, communication culture, communication channel
course divisions » court decisions, course designs, forest divisions
control course » control coupled, control case, control costs
gauge spaces » large space, safe spaces, use spaces
scale spaces » scale space, sample spaces
tuple spaces » tuple space, type spaces, triple 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 control course divisions ((((gauge spaces) OR (scale spaces))) OR (tuple spaces)).
• Adding a wildcard symbol may retrieve word variants: communication control course divisions ((((gauge spaces) or (scale spaces))) or (tuple spaces))*.
