Perhaps you should try some spelling variations:
idea transport » ideas transport, sea transport, de transport
transfer 3 » transfer 4, transfer a, transfer 3.2
guias der » guias de, guia de, bias der
der lange » der lander
key idea » key ideas, very idea, key item
costs la » costs a, costs land, costs _
values » value

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: (( values key idea transport costs la ) OR ( guias der lange ((transfer 3) OR (transfer _)) a ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( values key idea transport costs la ) or ( guias der lange ((transfer 3) OR (transfer _)) a ))~".
• Adding a wildcard symbol may retrieve word variants: (( values key idea transport costs la ) or ( guias der lange ((transfer 3) OR (transfer _)) a ))*.
