Perhaps you should try some spelling variations:
transform fuel » transport fuel, transform our, transform fft
transfer 4 » transfer _, transfer 3, transfer a
box ideas » big ideas, dos ideas
guias der » guias de, guia de, bias der
co ideas » core ideas, two ideas, dos ideas
der heat » der heimat, der heydt, der heute

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 ((co ideas) OR (box ideas)) transform fuel _ ) OR ( guias der heat transfer 4 a ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( areas ((co ideas) OR (box ideas)) transform fuel _ ) or ( guias der heat transfer 4 a ))~".
• Adding a wildcard symbol may retrieve word variants: (( areas ((co ideas) OR (box ideas)) transform fuel _ ) or ( guias der heat transfer 4 a ))*.
