Perhaps you should try some spelling variations:
information based » information case, information bank, transformation based
de communication » mobile communication, online communication
technologien 1 » technologies 1, technologien _, technologien 4
based wenn » based web, based wind, based werken
wenn de » wenn die, wenn du, wenn das
4 areal » _ areal, 2 areal, 4 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 1 information based wenn de communication costs _ developing ((4 areal) OR (4 real)).~".
• Adding a wildcard symbol may retrieve word variants: technologien 1 information based wenn de communication costs _ developing ((4 areal) OR (4 real)).*.
