Perhaps you should try some spelling variations:
heilkunde 1660 » heilkunde 10, heilkunde 6, heilkunde 11
heilkunde 16 » heilkunde 6, heilkunde 10, heilkunde 11
heilkunde 1 » heilkunde 10, heilkunde 11, heilkunde 18
vier.been.dt.good.hno-heilkunde » view.been.dt.good.hno-heilkunde
vers.been.dt.good.hno- » verse.been.dt.good.hno-, verso.been.dt.good.hno-, very.been.dt.good.hno-

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: (( vier.been.dt.good.hno-heilkunde 16 ) OR ( vers.been.dt.good.hno-((heilkunde 1660) OR (heilkunde 1)) )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( vier.been.dt.good.hno-heilkunde 16 ) or ( vers.been.dt.good.hno-((heilkunde 1660) OR (heilkunde 1)) ))".
• Adding a wildcard symbol may retrieve word variants: (( vier.been.dt.good.hno-heilkunde 16 ) or ( vers.been.dt.good.hno-((heilkunde 1660) OR (heilkunde 1)) ))*.
