Perhaps you should try some spelling variations:
information used » information use, information users, information based
technologies de » technologies _, technologies 4, technologies 2
de information » die information, de informacion, e information
developing 4 » developing _, developing a, developing e
ict case » ict cases, ict based, 1st case
4 areal » 4 real, _ areal, 2 areal

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 de information used ((ict case) OR (ict use)) communication a _ developing 4 areal.~".
• Adding a wildcard symbol may retrieve word variants: technologies de information used ((ict case) OR (ict use)) communication a _ developing 4 areal.*.
