Perhaps you should try some spelling variations:
information spaces » information sources, information series, information services
code dimensions » core dimensions, model dimensions, scope dimensions
array string » array strong, arrays strings, array sharing
spaces code » space code, spaces core, spaces model
array fermi » array forming

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 code dimensions ((((array format) or (array string))) or (array fermi))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: information spaces code dimensions ((((array format) OR (array string))) OR (array fermi)).
• Adding a wildcard symbol may retrieve word variants: information spaces code dimensions ((((array format) or (array string))) or (array fermi))*.
