也许你应该尝试一些拼写变化:
authorization authentication » information authentication
testing multidimensional » detecting multidimensional, using multidimensional, fitting multidimensional
authentication testing » authentication cheating, authentication using, authentication tests
array probing » arrays probing, assay probing, array profiling
array string » array strong, arrays strings, array sharing

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "authorization authentication testing multidimensional ((array string) OR (array probing))~".
• Adding a wildcard symbol may retrieve word variants: authorization authentication testing multidimensional ((array string) OR (array probing))*.
