Perhaps you should try some spelling variations:
1 communication » 10 communication, 3 communication, 4 communication
technologies 2 » technologies _, technologies 4
4.4 developing » 5.4 developing, 6.4 developing, 1.4 developing
information 2 » information 3
developing a » developing _
costs 4.4 » costs 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: "technologies 2 information 2 i 1 communication costs 4.4 developing a (aezs. OR sezs.)~".
• Adding a wildcard symbol may retrieve word variants: technologies 2 information 2 i 1 communication costs 4.4 developing a (aezs. OR sezs.)*.
