Perhaps you should try some spelling variations:
communication connection » communications connections, communication connecting, communication collections
connection methods » connection method, collection methods, correction methods
methods dimension » methods diffusion, ethics dimension, metholodgy dimension
whose spaces » phase spaces, shape spaces, loose space
tuple spaces » tuple space, type spaces, triple space
race » rate, 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 connection methods dimension ((((whose spaces) OR (whose race))) OR (tuple spaces))~.
• Adding a wildcard symbol may retrieve word variants: communication connection methods dimension ((((whose spaces) or (whose race))) or (tuple spaces))*.
