Perhaps you should try some spelling variations:
oral communication » personal communication
e transformation » de transformation, 1 transformation, die transformation
transformation 1 » transformation _, transformation a, transformation 3
technologie e » technologie de, technologie ve, technologie c
why oral » why rural, why deal
costs a » costs _, costs 4
e real » 4 real, 2 real, 3 real
1 why » _ why

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: "technologie e transformation 1 why oral communication costs a development ((e real) OR (1 real)).~".
• Adding a wildcard symbol may retrieve word variants: technologie e transformation 1 why oral communication costs a development ((e real) OR (1 real)).*.
