Perhaps you should try some spelling variations:
communication cross » communication costs
development based » development band, development case, development bank
a communication » la communication, data communication, data communications
c development » 2 development, 1 development, gcc development
based areas » base areas, based areal, basic areas
cross c » cross _, cross 1
2 air » _ air
2 aim » 2 aims, _ aim

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 _ information ((2 air) OR (2 aim)) a communication cross c development based areas.~".
• Adding a wildcard symbol may retrieve word variants: technologien _ information ((2 air) OR (2 aim)) a communication cross c development based areas.*.
