Perhaps you should try some spelling variations:
communication detection » communications detection, communication delegation, communication directions
detection methods » detection method, extraction methods, collection methods
methods diffusion » networks diffusion, methods decision
whose spaces » phase spaces, shape spaces, whose race
gauge spaces » large space, safe spaces, use spaces
type spaces » state 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 detection methods diffusion ((((whose spaces) OR (gauge spaces))) OR (type spaces))~.
• Adding a wildcard symbol may retrieve word variants: communication detection methods diffusion ((((whose spaces) or (gauge spaces))) or (type spaces))*.
