Perhaps you should try some spelling variations:
fermentation process » fermentation processes, fermentation products, fermentation profiles
learning dimensions » learning dimension, planning dimensions, learning tensions
process learning » problems learning, process planning, process mining
array probing » arrays probing, assay probing, array profiling
array using » arrays using

• If you are trying to use Boolean operators, they must be ALL CAPS: fermentation process learning dimensions ((((array using) OR (array probing))) OR (array format)).
• Adding a wildcard symbol may retrieve word variants: fermentation process learning dimensions ((((array using) or (array probing))) or (array format))*.
