也许你应该尝试一些拼写变化:
information documents » information documentation, information agents, information requirements
basics dimensions » basic dimensions, physics dimensions, based dimensions
documents basics » document basics, documents based, documentation basics
parton roger » barton roger, martin roger, norton roger
hartl roger » hart roger, haul roger, harald groger
hart robert » caret robert, herdt robert, east robert

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 basics dimensions ((((hartl roger) OR (hart robert))) OR (parton roger))~.
• Adding a wildcard symbol may retrieve word variants: information documents basics dimensions ((((hartl roger) or (hart robert))) or (parton roger))*.
