Perhaps you should try some spelling variations:
heilkunde 10 » heilkunde 1, heilkunde 16, heilkunde 18
heilkunde 11 » heilkunde 1, heilkunde 16, heilkunde 18
verh.been.dt.good.hno-heilkunde » ver.been.dt.good.hno-heilkunde, vers.been.dt.good.hno-heilkunde, verb.been.dt.good.hno-heilkunde

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( verh.been.dt.good.hno-heilkunde 10 ) OR ( very.been.dt.good.hno-heilkunde 11 ))".
• Adding a wildcard symbol may retrieve word variants: (( verh.been.dt.good.hno-heilkunde 10 ) OR ( very.been.dt.good.hno-heilkunde 11 ))*.
