Talvez debería tentar con algunhas variantes ortográficas:
information collection » information extraction, information communication
methods extending » networks extending, methods finding, methods enhancing
array formulas » area formulas, harrop formulas, array formats
array arcing » array forming, array probing, array sharing

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: information collection methods extending ((((array arcing) or (array formulas))) or (array format))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: information collection methods extending ((((array arcing) OR (array formulas))) OR (array format)).
• Adding a wildcard symbol may retrieve word variants: information collection methods extending ((((array arcing) or (array formulas))) or (array format))*.
