Perhaps you should try some spelling variations:
boues transport » bus transport, nodes transport, goods transport
transport cost » transport costs
land transfer » land transfers, land transport, funds transfer
transfer 4 » transfer _, transfer 3, transfer a
vagues de » vague de, values de, langues de
guias der » guias de, guia de
de boues » des boues, de bonnes, les boues
bias der » bias des, bias over, das der
cost a » cost _, cost 4, cost 5

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: (( vagues de boues transport cost a ) OR ( ((guias der) OR (bias der)) land transfer 4 a ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( vagues de boues transport cost a ) or ( ((guias der) OR (bias der)) land transfer 4 a ))~".
• Adding a wildcard symbol may retrieve word variants: (( vagues de boues transport cost a ) or ( ((guias der) OR (bias der)) land transfer 4 a ))*.
