Perhaps you should try some spelling variations:
teoria semantica » teoria quantica, theories semantics, media semantic
storia critica » historia critica, teoria critica, stories critical
storia antica » storia gotica, storia romantica, historia antiga
istituto di » instituto de, instituto ad
istituti di » instituti di, istituti pii, istituiti sic
%contributo » %contributor, %contribute, %contributi

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: "%contributo della%((istituto di) OR (istituti di)) ((((storia antica) OR (storia critica))) OR (teoria semantica))%22".
• Adding a wildcard symbol may retrieve word variants: %contributo della%((istituto di) OR (istituti di)) ((((storia antica) OR (storia critica))) OR (teoria semantica))%22*.
