Perhaps you should try some spelling variations:
communities formalization » communities organization, communities organizations, communities urbanization
formalization based » normalization based, formulation based, localization based
based extensible » based extension, based extensions, based reversible
array string » array strong, arrays strings, array sharing
array using » arrays using

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

• If you are trying to use Boolean operators, they must be ALL CAPS: communities formalization based extensible ((array string) OR (((array using) OR (array format))))~.
• Adding a wildcard symbol may retrieve word variants: communities formalization based extensible ((array string) or (((array using) or (array format))))*.
