Perhaps you should try some spelling variations:
touch communication » trough communication, truth communication, through communication
development plans » development planning, development policy, development policies
case development » care development, based development, scale development
technology 3 » technology _, technology 1, technology 4
3 relations » et relations, des relations
costs case » costs cash
3.1 6 » 3.1 _, 3.1 k, 3.1 i
3.1 a » 3.1 _, 2.1 a

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: "technology 3 relations ((3.1 6) OR (3.1 a)) touch communication costs case development plans _.~".
• Adding a wildcard symbol may retrieve word variants: technology 3 relations ((3.1 6) OR (3.1 a)) touch communication costs case development plans _.*.
