Talvez debería tentar con algunhas variantes ortográficas:
communication function » communication functions, communication foundation, communicative functions
based extraction » based interaction, phase extraction, based education
array string » array strong, arrays strings, array sharing
array arcing » array forming, array probing, array sharing
arrays ang » arrays a

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 function based extraction ((((array string) OR (array arcing))) OR (arrays ang))~.
• Adding a wildcard symbol may retrieve word variants: communication function based extraction ((((array string) or (array arcing))) or (arrays ang))*.
