Perhaps you should try some spelling variations:
scales communication » scale communication, states communications, called communication
communication 1 » communication _, communication a, communication 3
le development » e development, ce development, le developpement
development en » developpement en, development menu, development eco
pt 3 » pt 1
1 le » 1 les, 1 la, 3 le

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 _ information ((pt 3) OR (pt 2)) scales communication 1 le development en afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies _ information ((pt 3) OR (pt 2)) scales communication 1 le development en afrique.*.
