Talvez debería tentar con algunhas variantes ortográficas:
information space » information spaces, information search, information source
spaces expression » species expression, spaces expressing, pages expression
space spaces » space space, space species, spaces space
array string » array strong, arrays strings, array sharing
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 space spaces expression ((array string) OR (((array format) OR (array arcing))))~.
• Adding a wildcard symbol may retrieve word variants: information space spaces expression ((array string) or (((array format) or (array arcing))))*.
