Perhaps you should try some spelling variations:
information diffraction » information extraction, information diffusion, information interaction
diffraction methods » extraction methods
methods rules » methods role, methods results, methods tables
array forming » array format, array arcing, array fermi
array string » array strong, arrays strings, array sharing
array using » arrays using

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 diffraction methods rules ((((array string) OR (array forming))) OR (array using))~".
• Adding a wildcard symbol may retrieve word variants: information diffraction methods rules ((((array string) OR (array forming))) OR (array using))*.
