Perhaps you should try some spelling variations:
communication convergence » communications convergence, communications conference, communication consequences
convergence basic » convergence best, convergence fast, convergence iwasc
basic dimensions » based dimension, pacific dimensions, design dimensions
large spaces » larger spaces, gauge spaces, large scales
large space » large sparse, large scale, large surface
use spaces » tuple spaces, phase spaces, gauge spaces

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

• Performing a fuzzy search may retrieve terms with similar spellings: communication convergence basic dimensions ((((large spaces) or (use spaces))) or (large space))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication convergence basic dimensions ((((large spaces) OR (use spaces))) OR (large space)).
• Adding a wildcard symbol may retrieve word variants: communication convergence basic dimensions ((((large spaces) or (use spaces))) or (large space))*.
