Perhaps you should try some spelling variations:
information costs » information contents, information centers, information content
technologien fur » technologien des, technologien und, technologies 2
fur information » zur information, fair information, your information
developing 2 » developing _, developing a, developing e
2 areal » 2 real, _ areal, 2 areas
a 3.4 » a 3.3, a 3.1, _ 3.4
a 3.2 » _ 3.2, a 4.2

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 costs ((a 3.4) OR (a 3.2)) communication costs _ developing 2 areal.~".
• Adding a wildcard symbol may retrieve word variants: technologien fur information costs ((a 3.4) OR (a 3.2)) communication costs _ developing 2 areal.*.
