Perhaps you should try some spelling variations:
trade development » software development
a communication » la communication, data communication, data communications
communication 5 » communication _, communication a, communication 3
does variation » de variation, der variation, die variation
typology does » typologie des, apology do's, typology how
1 afrique » l afrique, en afrique, 1 enrique
5 trade » 1 trade, 4 trade, 2 trade

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: "typology does variation ((4 does) OR (2 does)) a communication 5 trade development 1 afrique.~".
• Adding a wildcard symbol may retrieve word variants: typology does variation ((4 does) OR (2 does)) a communication 5 trade development 1 afrique.*.
