Perhaps you should try some spelling variations:
using multidimensional » _ multidimensional, a multidimensional
information classes » information case, information asset, information assets
classes using » classifiers using, classifier using
array imaging » arrays imaging, airway imaging, ray imaging
array arcing » array forming, array probing, array sharing
array using » arrays using

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

• Performing a fuzzy search may retrieve terms with similar spellings: information classes using multidimensional ((array arcing) or (((array using) or (array imaging))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: information classes using multidimensional ((array arcing) OR (((array using) OR (array imaging)))).
• Adding a wildcard symbol may retrieve word variants: information classes using multidimensional ((array arcing) or (((array using) or (array imaging))))*.
