transfer auf » transfer aus, transfer a, transfer als
transport a » transport _, transport data
dem roman » der roman, diem romani, im roman
de roman » der roman, du roman, die romane
a asia » 3 asia, e asia, dan asia
luis a » luis f, luis c

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 ((de roman) OR (dem roman)) transport a asia ) OR ( luis a data transfer auf _ ))~.
• Adding a wildcard symbol may retrieve word variants: (( luis ((de roman) or (dem roman)) transport a asia ) or ( luis a data transfer auf _ ))*.
