Perhaps you should try some spelling variations:
informative ground » informative group, information grounds, informative compound
surface diffusion » state diffusion
ground surface » road surface, rough surface, ground source
array formats » array format, assay formats, array formulas
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.

• If you are trying to use Boolean operators, they must be ALL CAPS: informative ground surface diffusion ((array string) OR (((array formats) OR (array using))))~.
• Adding a wildcard symbol may retrieve word variants: informative ground surface diffusion ((array string) or (((array formats) or (array using))))*.
