Perhaps you should try some spelling variations:
information based » information case, information bank, transformation based
technologien fur » technologien des, technologien und, technologies 2
fur information » zur information, fair information, your information
a developing » a development
developing 4 » developing _, developing a, developing e
costs a » costs _, costs 4
4 areal » 4 real, _ areal, 2 areal
hdl 4 » hdl c, hdl 2, hdm 4

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 fur information based ((hdl 4) OR (hdl _)) communication costs a developing 4 areal.~".
• Adding a wildcard symbol may retrieve word variants: technologien fur information based ((hdl 4) OR (hdl _)) communication costs a developing 4 areal.*.
