Perhaps you should try some spelling variations:
sea transport » road transport, bus transport
transport 1 » transport _, transport a, transport 4
delad sea » dead sea
aguas del » aguas de, aguas do
del heat » fuel heat
der casa » der causa, der asa, der case
der cas » der case, der ca, der can
1 cao » 1 can, 1 ao, _ cao

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 delad sea transport 1 cao ) OR ( aguas del heat transfer ((der casa) OR (der cas)) ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( aguas delad sea transport 1 cao ) or ( aguas del heat transfer ((der casa) OR (der cas)) ))~".
• Adding a wildcard symbol may retrieve word variants: (( aguas delad sea transport 1 cao ) or ( aguas del heat transfer ((der casa) OR (der cas)) ))*.
