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

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: communication solution method extension ((((scale dspaces) or (scale space))) or (type dspaces))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication solution method extension ((((scale dspaces) OR (scale space))) OR (type dspaces)).
• Adding a wildcard symbol may retrieve word variants: communication solution method extension ((((scale dspaces) or (scale space))) or (type dspaces))*.
