Perhaps you should try some spelling variations:
formation process » formation processes, creation process, fermentation process
class dimensions » across dimensions, classes dimension, class extensions
process class » process claims, process case, process cases
array formats » assay formats, array formulas, ready formats
array string » array strong, arrays strings, array sharing

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

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