Perhaps you should try some spelling variations:
heat transport » sea transport, clean transport, road transport
transfer beim » transfer bei, transfers bei, transfer axiom
costs across » scores across, risks across
rene heat » rice heat
a net » a new, _ net
a neo » a new, _ neo
macao » macro, macau, cacao

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: (( luis rene heat transport costs across ) OR ( luis ((a net) OR (a neo)) transfer beim macao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis rene heat transport costs across ) or ( luis ((a net) OR (a neo)) transfer beim macao ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis rene heat transport costs across ) or ( luis ((a net) OR (a neo)) transfer beim macao ))*.
