Talvez debería tentar con algunhas variantes ortográficas:
communication applications » communication education, education applications
applications basis » applications basics, applications basic, applications based
basis extension » basins extension, basic extension, basics extensions
array range » ray range
arrays ang » arrays a
array a » array _

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 applications basis extension ((((array a) OR (array range))) OR (arrays ang))~.
• Adding a wildcard symbol may retrieve word variants: communication applications basis extension ((((array a) or (array range))) or (arrays ang))*.
