Perhaps you should try some spelling variations:
heilkunde 16 » heilkunde 6, heilkunde 10, heilkunde 11
heilkunde 1 » heilkunde 10, heilkunde 11, heilkunde 18
verh.bern.dt.geld.hno-heilkunde » ver.bern.dt.geld.hno-heilkunde, vers.bern.dt.geld.hno-heilkunde, vera.bern.dt.geld.hno-heilkunde, verh.ben.dt.geld.hno-heilkunde, verh.bern.dt.gold.hno-heilkunde, verh.bern.dt.gel.hno-heilkunde
very.been.dt.geld.hno-heilkunde » very.been.dt.gold.hno-heilkunde, very.been.dt.gel.hno-heilkunde
verb.born.dt.gels.hno- » ver.born.dt.gels.hno-, vers.born.dt.gels.hno-, verb.born.dt.gel.hno-, verb.born.dt.gets.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.geld.hno-heilkunde OR very.been.dt.geld.hno-heilkunde) 1991 ) OR ( verb.born.dt.gels.hno-((heilkunde 1) OR (heilkunde 16)) )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( (verh.bern.dt.geld.hno-heilkunde or very.been.dt.geld.hno-heilkunde) 1991 ) or ( verb.born.dt.gels.hno-((heilkunde 1) OR (heilkunde 16)) ))".
• Adding a wildcard symbol may retrieve word variants: (( (verh.bern.dt.geld.hno-heilkunde or very.been.dt.geld.hno-heilkunde) 1991 ) or ( verb.born.dt.gels.hno-((heilkunde 1) OR (heilkunde 16)) ))*.
