Perhaps you should try some spelling variations:
communications collected » communication collected, communications selected, complications collected
collected methods » collection methods, selected methods, oriented methods
methods dimension » methods diffusion, ethics dimension, metholodgy dimension
whose spaces » phase spaces, shape spaces, whose race
safe spaces » state spaces, shape spaces, scale 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: communications collected methods dimension ((((whose spaces) OR (safe spaces))) OR (type spaces))~.
• Adding a wildcard symbol may retrieve word variants: communications collected methods dimension ((((whose spaces) or (safe spaces))) or (type spaces))*.
