Perhaps you should try some spelling variations:
technologien road » technologien ad, technologien und, technologien am
information case » information based, information can, information costs
e communication » de communication, 1 communication, une communication
e areas » 1 areas, 2 areas
4 areas » 1 areas, 2 areas, 4 areal
case d » case 1, case 2, case 3

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 road information case d e communication costs _ developing ((e areas) OR (4 areas)).~".
• Adding a wildcard symbol may retrieve word variants: technologien road information case d e communication costs _ developing ((e areas) OR (4 areas)).*.
