Perhaps you should try some spelling variations:
transport schemes » transfer schemes, transfers schemes, transport systems
vi transformed » _ transformed, a transformed, have transformed
cas transport » car transport, gas transport, mass transport
schemes use » scheme use, schemas used, schemes one
langues de » langue de, langages de, langue du
vagues dm » vagues de
vague de » vagues de, langue de, vue de
dm vi » dm vii, dm ii, dm v

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: (( ((langues de) OR (vague de)) cas transport schemes use ) OR ( vagues dm vi transformed _ cao ))~.
• Adding a wildcard symbol may retrieve word variants: (( ((langues de) or (vague de)) cas transport schemes use ) or ( vagues dm vi transformed _ cao ))*.
