Perhaps you should try some spelling variations:
communication applications » communication education, education applications
applications based » application based
based extension » based extraction
array along » arrays long, array arcing, array paving
array range » ray range
arrays ang » arrays a

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "communication applications based extension ((((array along) OR (array range))) OR (arrays ang))~".
• Adding a wildcard symbol may retrieve word variants: communication applications based extension ((((array along) OR (array range))) OR (arrays ang))*.
