Perhaps you should try some spelling variations:
information interaction » information integration, information interacting, information extraction
interaction systems » interaction system, interactive systems, injection systems
systems recursion » systems recursive, systems decision, systems reduction
array forming » array arcing, array formats, array string

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

• Performing a fuzzy search may retrieve terms with similar spellings: information interaction systems recursion ((((array fermi) OR (array forming))) or (array format))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: information interaction systems recursion ((((array fermi) OR (array forming))) OR (array format)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "information interaction systems recursion ((((array fermi) OR (array forming))) or (array format))".
• Adding a wildcard symbol may retrieve word variants: information interaction systems recursion ((((array fermi) OR (array forming))) or (array format))*.
