Perhaps you should try some spelling variations:
communication cross » communication costs
technologien stm » technologien am, technologien im, technologien ist
stm information » crm information, system information, from information
information b » information 2, information 1, information bank
c development » 2 development, 1 development, gcc development
aid debt » aid debate, card debt, hard debt
cross c » cross _, cross 1
a areas » 1 areas, 2 areas, 4 areas
aid de » aid do, aid does

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 stm information b ((aid de) OR (aid debt)) communication cross c development a areas.~".
• Adding a wildcard symbol may retrieve word variants: technologien stm information b ((aid de) OR (aid debt)) communication cross c development a areas.*.
