Perhaps you should try some spelling variations:
data transfer » cash transfer, heat transfer
sea transport » road transport, bus transport
values de » values add, values _, values a
costs dam » cost dam, costs data, costs a
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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( values de sea transport costs dam ) OR ( guia age data transfer from schaum ))~".
• Adding a wildcard symbol may retrieve word variants: (( values de sea transport costs dam ) OR ( guia age data transfer from schaum ))*.
