Perhaps you should try some spelling variations:
transport air » transport a, transport data, transport _
transfer der » transfer fees, transfer _
dem roman » der roman, diem romani, im roman
de roman » der roman, du roman, die romane
air asa » air asia, air mass, air base
luis a » luis f, luis c
a heat » a heart, _ heat, a head
der a » der _, der e

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: (( aus ((de roman) OR (dem roman)) transport air asa ) OR ( luis a heat transfer der a ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( aus ((de roman) OR (dem roman)) transport air asa ) or ( luis a heat transfer der a ))~".
• Adding a wildcard symbol may retrieve word variants: (( aus ((de roman) OR (dem roman)) transport air asa ) or ( luis a heat transfer der a ))*.
