Talvez debería tentar con algunhas variantes ortográficas:
communications contention » communications convention, communication contention, communications connections
contention based » content based, attention based, condition based
based dimension » based dispersion, basic dimensions, based extension
large spaces » larger spaces, large scales, range spaces
gauge spaces » safe spaces, use spaces
large space » large sparse, large scale, large surface

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

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