Perhaps you should try some spelling variations:
lao communications » laos communications, faso communications, do communications
der developpement » de developpement, des developpements, leur developpement
developpement du » developpement de, developpement des, developpement et
technologies 1 » technologies _, technologies 4, technologies 2
du afrique » en afrique, l afrique, de l'afrique
pt 13 » pt 1, pt 10, pt 11
pt 3 » pt 2, pt 1

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: "technologies 1 information ((pt 13) OR (pt 3)) lao communications _ der developpement du afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies 1 information ((pt 13) OR (pt 3)) lao communications _ der developpement du afrique.*.
