Perhaps you should try some spelling variations:
communicative function » communicative functions, communication function, communication functions
based extraction » based interaction, phase extraction, based education
array arcing » array forming, array probing, array sharing
array fermi » array forming, array format
arrays a » arrays _

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