Perhaps you should try some spelling variations:
information bank » information b, information 2, information 1
de communication » mobile communication, online communication
1 developing » 3 developing, 4 developing, 2 developing
bank wenn » banken wenn, bank win, bank bern
wenn de » wenn die, wenn du, wenn das
costs 1 » costs _, costs 4, costs a
4 areal » 4 real, _ areal, 4 areas
2 areal » 2 real, _ areal, 2 areas

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "technologien _ information bank wenn de communication costs 1 developing ((4 areal) OR (2 areal)).~".
• Adding a wildcard symbol may retrieve word variants: technologien _ information bank wenn de communication costs 1 developing ((4 areal) OR (2 areal)).*.
