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, 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.

• Performing a fuzzy search may retrieve terms with similar spellings: communication collection methods dimension ((((whose spaces) OR (whose race))) or (tuple spaces))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication collection methods dimension ((((whose spaces) OR (whose race))) OR (tuple spaces))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "communication collection methods dimension ((((whose spaces) OR (whose race))) or (tuple spaces))*".
