Perhaps you should try some spelling variations:
communication information » communication international, communication education
from extensive » from intensive, from inexpensive, non extensive
array sharing » arrays bearing, array imaging, way sharing
array string » arrays strings, array forming, array using
array strong » norway strong, stay strong, array along

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: communication information from extensive ((array sharing) OR (((array string) OR (array strong))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "communication information from extensive ((array sharing) or (((array string) OR (array strong))))~".
• Adding a wildcard symbol may retrieve word variants: communication information from extensive ((array sharing) or (((array string) OR (array strong))))*.
