transport tvdft » transform tvdft
sea transport » road transport, bus transport
areas coal » areas can, areas co
transfer 3 » transfer _, transfer a, transfer 3.2
transfer 4 » transfer _, transfer a, transfer der
coal sea » coal seam, coal seams, coal use
guide de » guide _, guide a, guide 1
de das » die das, ee das, de datos

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: (( areas coal sea transport tvdft _ ) OR ( guide de das ((transfer 3) OR (transfer 4)) ao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( areas coal sea transport tvdft _ ) or ( guide de das ((transfer 3) OR (transfer 4)) ao ))~".
• Adding a wildcard symbol may retrieve word variants: (( areas coal sea transport tvdft _ ) or ( guide de das ((transfer 3) OR (transfer 4)) ao ))*.
