Perhaps you should try some spelling variations:
separation processing » preparation processing, preparations processing, separation processes
processing based » processing case, process based
based dimensions » based dimension, basic dimensions, based dimensioning
array formulas » area formulas, harrop formulas, array formats
array probing » arrays probing, assay probing, array profiling

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

• Performing a fuzzy search may retrieve terms with similar spellings: separation processing based dimensions ((((array format) or (array formulas))) or (array probing))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: separation processing based dimensions ((((array format) OR (array formulas))) OR (array probing)).
• Adding a wildcard symbol may retrieve word variants: separation processing based dimensions ((((array format) or (array formulas))) or (array probing))*.
