Perhaps you should try some spelling variations:
transfer fees » transfer from
ion transport » road transport, main transport, bus transport
transfer der » transfer _
transport en » transport et, transport can, transport _
de ion » de iones
care » case
cada » scada, ada, coda

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: (( guias care data ((transfer der) OR (transfer fees)) a ) OR ( guia de ion transport en cada ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( guias care data ((transfer der) OR (transfer fees)) a ) or ( guia de ion transport en cada ))~".
• Adding a wildcard symbol may retrieve word variants: (( guias care data ((transfer der) OR (transfer fees)) a ) or ( guia de ion transport en cada ))*.
