Perhaps you should try some spelling variations:
communication solution » communication solutions, communications solution, communication evolution
method dimension » methods dimension, metric dimension, method extension
solution method » solution methods, evaluation method
scale dspaces » scale spaces, scale impacts, scale devices
type spaces » state spaces
dspaces » ddspaces
space » dspace
spaces » dspaces

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 solution method dimension ((((scale dspaces) OR (scale space))) OR (type spaces))~.
• Adding a wildcard symbol may retrieve word variants: communication solution method dimension ((((scale dspaces) or (scale space))) or (type spaces))*.
