也许你应该尝试一些拼写变化:
information documents » information documentation, information agents, information requirements
control extensions » central extensions, central extension, control extending
documents control » documents contracts, document context, documents common
array profiling » array processing, microarray profiling
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.

• Performing a fuzzy search may retrieve terms with similar spellings: information documents control extensions ((((array profiling) or (array using))) or (array string))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: information documents control extensions ((((array profiling) OR (array using))) OR (array string)).
• Adding a wildcard symbol may retrieve word variants: information documents control extensions ((((array profiling) or (array using))) or (array string))*.
