也许你应该尝试一些拼写变化:
communication concepts » communication circuits, communication congresses, communication channels
central dimensions » cultural dimensions, ceintric dimensions, central extensions
concepts central » concepts general, concepts spectral, concepts chemical
larger spaces » larger species, large space, larger scale
large spaces » large space, gauge spaces, range spaces
large scales » large scale, large scaled, larger scale

• If you are trying to use Boolean operators, they must be ALL CAPS: communication concepts central dimensions ((((large spaces) OR (large scales))) OR (larger spaces)).
• Adding a wildcard symbol may retrieve word variants: communication concepts central dimensions ((((large spaces) or (large scales))) or (larger spaces))*.
