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