Perhaps you should try some spelling variations:
communication cross » communication costs
development base » development based, development case, development cases
a communication » la communication, data communication, data communications
technologien 1 » technologies 1, technologien _, technologien 4
base areas » basic areas, based areal, basin areas
cross 2 » cross _, cross 1, cross c
2 air » 2 aim
_ air » _ aid

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