Perhaps you should try some spelling variations:
persona communication » personal communication, personal communications, personal communicator
le developpement » de developpement, sme development
developpement en » developpement et, developpement des, developpement de
typology data » hydrology data, typology a, typology alma
6 die » 3 die, _ die, 1 die
a le » a les, a la, a l

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 data variables ((6 die) OR (2 die)) persona communication a le developpement en afrique.~".
• Adding a wildcard symbol may retrieve word variants: typology data variables ((6 die) OR (2 die)) persona communication a le developpement en afrique.*.
