a communication » la communication, data communication, data communications
1 development » 2 development, 3.1 development, mena development
basic areas » basin area, basic ideas, basic access
cross 1 » cross _, cross c
2 air » _ air, 2 aim
2 ai » 2 aim, 2 a, _ ai

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 ai) OR (2 air)) a communication cross 1 development basic areas.~".
• Adding a wildcard symbol may retrieve word variants: technologien _ information ((2 ai) OR (2 air)) a communication cross 1 development basic areas.*.
