Perhaps you should try some spelling variations:
authorization authentication » information authentication
access multidimensional » aspects multidimensional, schemes multidimensional, tables multidimensional
authentication access » authentication codes, authentication case, authentication analysis
array string » array strong, arrays strings, array sharing
array arcing » array forming, array probing, array sharing

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: authorization authentication access multidimensional ((array string) OR (array arcing))~.
• Adding a wildcard symbol may retrieve word variants: authorization authentication access multidimensional ((array string) or (array arcing))*.
