Perhaps you should try some spelling variations:
communication case » communication channels, communication culture
euclidean spaces » euclidean space
euclidean phase » euclidean case, euclidean space, euclidean half
euclidean plane » euclidean space
a motions » a motion, _ motions, i motions

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

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