euclidean spaces » euclidean space
euclidean half » euclidean ball, euclidean phase
euclidean case » euclidean phase, euclidean ramsey, euclidean space

cross a » cross _, cross arm

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