Perhaps you should try some spelling variations:
information aggregation » information integration, information propagation, information organization
aggregation soft » aggregation some, aggregation state, aggregation point
soft dimension » fifth dimension, next dimension
array string » array strong, array sharing, array forming
array fermi » array forming, array format

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

• Performing a fuzzy search may retrieve terms with similar spellings: information aggregation soft dimension ((((arrays strings) or (array fermi))) or (array string))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: information aggregation soft dimension ((((arrays strings) OR (array fermi))) OR (array string)).
• Adding a wildcard symbol may retrieve word variants: information aggregation soft dimension ((((arrays strings) or (array fermi))) or (array string))*.
