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
developing e » developing _, developing a, developing east
some deep » home deep, some deeper
costs 3 » costs 4, costs a, costs 5
e areas » 1 areas, 2 areas, 4 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) OR (costs _)) developing e areas.~".
• Adding a wildcard symbol may retrieve word variants: technologies 2 information some deep 4 communication ((costs 3) OR (costs _)) developing e areas.*.
