Talvez debería tentar con algunhas variantes ortográficas:
information ground » information grounds, information group, information grid
source diffusion » resource diffusion, surface diffusion, double diffusion
ground source » sound source, ground surface, sound sources
array formats » array format, assay formats, array formulas
array string » array strong, arrays strings, array sharing
array arcing » array forming, array probing, array sharing

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

• Performing a fuzzy search may retrieve terms with similar spellings: information ground source diffusion ((array string) or (((array formats) or (array arcing))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: information ground source diffusion ((array string) OR (((array formats) OR (array arcing)))).
• Adding a wildcard symbol may retrieve word variants: information ground source diffusion ((array string) or (((array formats) or (array arcing))))*.
