Perhaps you should try some spelling variations:
c's communication » lea's communication, class communication, mass communication
development does » development data, development 1, development 1.1
d development » ed development, 1 development, led development
does africa » zones africa, does america, dress africa
labor a » labor _
media d » media _, media 1, media 3

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 _ local ((labor ban) OR (labor a)) c's communication media d development does africa.~".
• Adding a wildcard symbol may retrieve word variants: technologien _ local ((labor ban) OR (labor a)) c's communication media d development does africa.*.
