Perhaps you should try some spelling variations:
communication collection » communication collections, communication connection, communication collective
methods dimension » methods diffusion, ethics dimension, metholodgy dimension
whose spaces » phase spaces, shape spaces, whose race
tuple spaces » tuple space, type spaces, triple space
whose rice » whose race, whose voice, white rice

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 collection methods dimension ((((whose spaces) OR (whose rice))) OR (tuple spaces))~.
• Adding a wildcard symbol may retrieve word variants: communication collection methods dimension ((((whose spaces) or (whose rice))) or (tuple spaces))*.
