Perhaps you should try some spelling variations:
secunda secundae » secundam secundae
quaestio 90 » quaestio de, quaestio _, quaestio ex
quaestio 47 » quaestio de, quaest 47, quaestio _
quaestio 3 » quaestio _, quaestio de, quaestio ex

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: thomas / aquinas, saint / 1225?-1274 / summa theologica / secunda secundae / ((((quaestio 3) OR (quaestio 90))) OR (quaestio 47))-171.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thomas / aquinas, saint / 1225?-1274 / summa theologica / secunda secundae / ((((quaestio 3) OR (quaestio 90))) or (quaestio 47))-171".
• Adding a wildcard symbol may retrieve word variants: thomas / aquinas, saint / 1225?-1274 / summa theologica / secunda secundae / ((((quaestio 3) OR (quaestio 90))) or (quaestio 47))-171*.
