information en » informacion en, information eine, information 2
development li » development lid, development lie, development lin
li afrique » l afrique, en afrique

• The words AND, OR and NOT may confuse the search; try adding quotes: "technologies _ information en ((3 style) OR (2 style)) communication 5 sme development li afrique.~".
• Adding a wildcard symbol may retrieve word variants: technologies _ information en ((3 style) OR (2 style)) communication 5 sme development li afrique.*.
