Perhaps you should try some spelling variations:
de communication » mobile communication, online communication
developpement et » developpement des, developpement de, development east
information als » information age, information a, information act
et matrice » et maitrise, la matrice, beta matrices
die de » die die, die der, die den
a set » _ set
a et » a net, a bet, a jet

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 als die de communication ((a et) OR (a set)) developpement et matrice.~".
• Adding a wildcard symbol may retrieve word variants: technologies _ information als die de communication ((a et) OR (a set)) developpement et matrice.*.
