Perhaps you should try some spelling variations:
transport cost » transport costs
sea transport » road transport, bus transport
data transfer » cash transfer, heat transfer
values de » values add, values _, values a
cost dam » cost data, cost a, cost dna
guia age » guia de
age data » wage data, cge data, image data
de sea » de ses, de ser
schaum » schaus

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: (( values de sea transport cost dam ) OR ( guia age data transfer from schaum ))~.
• Adding a wildcard symbol may retrieve word variants: (( values de sea transport cost dam ) or ( guia age data transfer from schaum ))*.
