Perhaps you should try some spelling variations:
institutionen des » institutionen der
historia antiga » historia antigua, historia antiqua, historia argentina
istituiti sic » istituti di
institut der » institut fur
istituti pii » istituti di, instituti di, istituto per
istituto di » instituto de, instituto ad
%contributo » %contributor, %contribute, %contributi

Try widening your search to All Fields.

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: %contributo della%((((istituto di) OR (((institut der) OR (institutionen des))))) OR (((istituti pii) OR (istituiti sic)))) historia antiga%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%contributo della%((((istituto di) or (((institut der) or (institutionen des))))) or (((istituti pii) OR (istituiti sic)))) historia antiga%22".
• Adding a wildcard symbol may retrieve word variants: %contributo della%((((istituto di) or (((institut der) or (institutionen des))))) or (((istituti pii) OR (istituiti sic)))) historia antiga%22*.
