Perhaps you should try some spelling variations:
information some » information source, information stored, information space
4 communication » 3 communication, 5.4 communication, de communication
technologies 2 » technologies _, technologies 4
3 developing » 3 development
some deep » home deep, some deeper
costs 3 » costs _, costs 4, costs a
2 areas » 2 areal, 4 areas, 2.1 areas
1 areas » 1 area, 4 areas, 2.1 areas
deep 4 » deep _, deep q

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: "technologies 2 information some deep 4 communication costs 3 developing ((2 areas) OR (1 areas)).~".
• Adding a wildcard symbol may retrieve word variants: technologies 2 information some deep 4 communication costs 3 developing ((2 areas) OR (1 areas)).*.
