Talvez debería tentar con algunhas variantes ortográficas:
information spaces » information sources, information series, information services
2 dimensional » _ dimensional, 3 dimensional, two dimensional
array probing » arrays probing, assay probing, array profiling
array string » array strong, arrays strings, array sharing
spaces 2 » spaces _, spaces a, spaces 3

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

• Performing a fuzzy search may retrieve terms with similar spellings: information spaces 2 dimensional ((((array format) or (array probing))) or (array string))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: information spaces 2 dimensional ((((array format) OR (array probing))) OR (array string)).
• Adding a wildcard symbol may retrieve word variants: information spaces 2 dimensional ((((array format) or (array probing))) or (array string))*.
