surface diffusion » state diffusion
ground surface » road surface, rough surface, ground source
array imaging » arrays imaging, airway imaging, ray imaging
array arcing » array forming, array probing, array sharing

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