Perhaps you should try some spelling variations:
cooperation a » cooperation _, cooperation et, cooperation fast
array forming » array format, array arcing, array fermi
a dimensions » _ dimensions, 2 dimensions, 3 dimensions
array strong » array sharing, norway strong, stay strong
array string » arrays strings, array sharing, array using

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

• If you are trying to use Boolean operators, they must be ALL CAPS: international cooperation a dimensions ((array strong) OR (((array string) OR (array forming))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "international cooperation a dimensions ((array strong) or (((array string) OR (array forming))))~".
• Adding a wildcard symbol may retrieve word variants: international cooperation a dimensions ((array strong) or (((array string) OR (array forming))))*.
