Talvez debería tentar con algunhas variantes ortográficas:
information grid » information guide, information gain, information gis
source diffusion » resource diffusion, surface diffusion, double diffusion
array formulas » area formulas, harrop formulas, array format
array probing » arrays probing, assay probing, array profiling
array string » array strong, arrays strings, array sharing
grid source » grid resource, acid source, good source

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 grid source diffusion ((array string) OR (((array formulas) OR (array probing))))~.
• Adding a wildcard symbol may retrieve word variants: information grid source diffusion ((array string) or (((array formulas) or (array probing))))*.
