Talvez debería tentar con algunhas variantes ortográficas:
communications convention » communications connections, communication connection, communication conversation
convention based » contention based, conversion based, conversation based
based dimension » based dispersion, basic dimensions, based extension
range spaces » range states, large spaces, tangent 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.

• If you are trying to use Boolean operators, they must be ALL CAPS: communications convention based dimension ((((range spaces) OR (gauge spaces))) OR (large space))~.
• Adding a wildcard symbol may retrieve word variants: communications convention based dimension ((((range spaces) or (gauge spaces))) or (large space))*.
