Perhaps you should try some spelling variations:
several dimensions » temporal dimensions, external dimensions, integral dimensions
information a » information age
array imaging » arrays imaging, airway imaging, ray imaging
array string » array strong, arrays strings, array sharing
a several » _ several, 3 several, 5 several

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "information a several dimensions ((array string) OR (array imaging))~".
• Adding a wildcard symbol may retrieve word variants: information a several dimensions ((array string) OR (array imaging))*.
