Perhaps you should try some spelling variations:
information diffraction » information extraction, information diffusion, information interaction
diffraction methods » extraction methods
methods sources » methods series, methods studies, methods survey
arrays imaging » array imaging, assays imaging, pathways imaging
array string » array strong, arrays strings, array sharing
array fermi » array forming, array format

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: information diffraction methods sources ((((array string) OR (array fermi))) OR (arrays imaging))~.
• Adding a wildcard symbol may retrieve word variants: information diffraction methods sources ((((array string) or (array fermi))) or (arrays imaging))*.
