Perhaps you should try some spelling variations:
implementation system » implementation systems, implementation state, implementation step
system report » systems report, system support, ecosystems report
array arcing » array forming, array probing, array sharing
array string » array strong, arrays strings, array sharing
formulation » formation

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

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