Talvez debería tentar con algunhas variantes ortográficas:
communication communications » communication communication, communication communicating, communications communication
communications hat » communications what, communications a, communications how
hat dimension » a dimension, tacit dimension, pit dimensions
range spaces » range states, large spaces, tangent spaces
gauge spaces » large space, safe spaces
use spaces » tuple spaces, phase spaces, whose 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 communications hat dimension ((range spaces) OR (((gauge spaces) OR (use spaces))))~.
• Adding a wildcard symbol may retrieve word variants: communication communications hat dimension ((range spaces) or (((gauge spaces) or (use spaces))))*.
