Perhaps you should try some spelling variations:
heilkunde 65.15 » heilkunde 15.15, heilkunde 5.1
heilkunde 6 » heilkunde 3, heilkunde _, heilkunde im
verh.bern.dt.gel.hno- » very.bern.dt.gel.hno-, ver.bern.dt.gel.hno-, vers.bern.dt.gel.hno-, verh.been.dt.gel.hno-, verh.born.dt.gel.hno-, verh.ben.dt.gel.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: verh.bern.dt.gel.hno-((heilkunde 65.15) OR (heilkunde 6)).
• Adding a wildcard symbol may retrieve word variants: verh.bern.dt.gel.hno-((heilkunde 65.15) or (heilkunde 6))*.
