也许你应该尝试一些拼写变化:
information documents » information documentation, information agents, information requirements
documents upper » documents under, documents used, documents after
upper dimension » popper dimension, user dimension, deeper dimension
array profiling » array processing, microarray profiling
array string » array strong, arrays strings, array sharing
array along » arrays long, array arcing, array paving

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: information documents upper dimension ((array along) OR (((array string) OR (array profiling))))~.
• Adding a wildcard symbol may retrieve word variants: information documents upper dimension ((array along) or (((array string) or (array profiling))))*.
