Talvez debería tentar con algunhas variantes ortográficas:
introduction description » introduction definition, introduction decision, introduction section
description method » description methods, descriptive methods, transcription method
method recursive » methods recursive, method discursive, other recursive
array forming » array format, array fermi, array formats
array arcing » array probing, array sharing, array using

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: introduction description method recursive ((array forming) OR (array arcing))~.
• Adding a wildcard symbol may retrieve word variants: introduction description method recursive ((array forming) or (array arcing))*.
