也许你应该尝试一些拼写变化:
information documents » information documentation, information agents, information requirements
centered prediction » centered prevention, centered education, content prediction
documents centered » document centered, documents entered, documents contained
based linear » based nonlinear, based library, based lead
basic linear » quasi linear, basic life
basics clear » basic nuclear

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 centered prediction ((((based linear) or (basic linear))) or (basics clear))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: information documents centered prediction ((((based linear) OR (basic linear))) OR (basics clear)).
• Adding a wildcard symbol may retrieve word variants: information documents centered prediction ((((based linear) or (basic linear))) or (basics clear))*.
