Perhaps you should try some spelling variations:
large transfers » large transfer, large transverse, barge transfer
transport cost » transport costs
der large » very large, over large, few large
de boues » des boues, de bonnes, les boues
bias der » bias des, bias over, das der
de bus » de busca
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: (( aguas ((de bus) OR (de boues)) transport cost a ) OR ( bias der large transfers _ do ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( aguas ((de bus) OR (de boues)) transport cost a ) or ( bias der large transfers _ do ))~".
• Adding a wildcard symbol may retrieve word variants: (( aguas ((de bus) OR (de boues)) transport cost a ) or ( bias der large transfers _ do ))*.
