information find » information field, information finding, information first
array profiling » array processing, microarray profiling
find surface » fine surfaces, fixed surface, land surface
array string » array strong, arrays strings, array sharing
array arcing » array forming, array probing, array sharing

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