Talvez debería tentar con algunhas variantes ortográficas:
communication connection » communications connections, communication connecting, communication collections
connection methods » connection method, collection methods, correction methods
methods dimension » methods diffusion, ethics dimension, metholodgy dimension
state spaces » state space
use spaces » tuple spaces, phase spaces, gauge spaces
race » rate, rice

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

• Performing a fuzzy search may retrieve terms with similar spellings: communication connection methods dimension ((((use spaces) or (whose race))) or (state spaces))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication connection methods dimension ((((use spaces) OR (whose race))) OR (state spaces)).
• Adding a wildcard symbol may retrieve word variants: communication connection methods dimension ((((use spaces) or (whose race))) or (state spaces))*.
