Perhaps you should try some spelling variations:
donatism » donatists, donating, donatus, donatosm
donatosm » donatismo, donatorum, donato
donati » donato
donation » donatoon
dogmatism » dogmatisch, dogmatik, dogmatic

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: (((donatism OR donatosm) OR (donati OR donation)) OR dogmatism)*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((donatism OR donatosm) or (donati or donation)) or dogmatism)*".
