Talvez debería tentar con algunhas variantes ortográficas:
information propagation » information presentation, information organization
propagation based » propagation case, propagation a, propagation due
based extraction » based interaction, phase extraction, based education
array formats » assay formats, array formulas, ready formats
array arcing » array forming, array probing, array sharing

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: information propagation based extraction ((((array arcing) OR (array formats))) OR (array format))~.
• Adding a wildcard symbol may retrieve word variants: information propagation based extraction ((((array arcing) or (array formats))) or (array format))*.
