der transport » de transport, den transport, door transport
transfer 3 » transfer _, transfer 4, transfer a
areas act » areas a, areas air, areas co
red head » red dead, red thread, red sea
act der » act does
firms a » firms _
de head » her head, per head

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 act der transport firms a ) OR ( guias ((de head) OR (red head)) transfer 3 a ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( areas act der transport firms a ) or ( guias ((de head) OR (red head)) transfer 3 a ))~".
• Adding a wildcard symbol may retrieve word variants: (( areas act der transport firms a ) or ( guias ((de head) OR (red head)) transfer 3 a ))*.
