cities east » cities case, societies east, cities adapt
bei mark » bei marc, bei maria, bei carl
luis a » 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 a _ transfer ((bei mark) OR (bei marx)) ) OR ( luis f data transform cities east ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis a _ transfer ((bei mark) OR (bei marx)) ) or ( luis f data transform cities east ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis a _ transfer ((bei mark) OR (bei marx)) ) or ( luis f data transform cities east ))*.
