Perhaps you should try some spelling variations:
donatism » donatists, donatus, donatum, donatosm
donating » donations, donatong
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 donating) OR (donati OR donation)) OR dogmatism)*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((donatism OR donating) or (donati or donation)) or dogmatism)*".
