Perhaps you should try some spelling variations:
heilkunde 16 » heilkunde 6, heilkunde 10, heilkunde 11
heilkunde 1 » heilkunde 10, heilkunde 11, 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.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( verh.been.dt.good.hno-heilkunde 1 ) OR ( very.been.dt.good.hno-heilkunde 16 )).
• Adding a wildcard symbol may retrieve word variants: (( verh.been.dt.good.hno-heilkunde 1 ) or ( very.been.dt.good.hno-heilkunde 16 ))*.
