Talvez debería tentar con algunhas variantes ortográficas:
information about » information age, information a
surface extension » surfaces extension, surface tension, surface expression
about surface » about space, root surface, about service
array string » array strong, arrays strings, array sharing
array using » arrays using
array fermi » array forming, array format

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 about surface extension ((((array string) OR (array using))) OR (array fermi))~.
• Adding a wildcard symbol may retrieve word variants: information about surface extension ((((array string) or (array using))) or (array fermi))*.
