Perhaps you should try some spelling variations:
e technologies » edge technologies, core technologies, dome technologies
la didactica » a didactic, a didactical, alla didattica
la didactic » a didactic, _ didactic, 1 didactic
didattica » didactics

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: media e technologies de ((((la didactic) OR (la didactica))) OR (la didattica)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "media e technologies de ((((la didactic) OR (la didactica))) or (la didattica))".
• Adding a wildcard symbol may retrieve word variants: media e technologies de ((((la didactic) OR (la didactica))) or (la didattica))*.
