Perhaps you should try some spelling variations:
heilkunde 5.1 » heilkunde 1, heilkunde 31, heilkunde 4.8
heilkunde 11 » heilkunde 1, heilkunde 10, heilkunde 16
vers.born.dt.ges.hno-heilkunde » verse.born.dt.ges.hno-heilkunde, verso.born.dt.ges.hno-heilkunde, very.born.dt.ges.hno-heilkunde, vers.born.dt.gets.hno-heilkunde, vers.born.dt.gels.hno-heilkunde, vers.born.dt.gems.hno-heilkunde
verh.born.dt.gem.hno-heilkunde » very.born.dt.gem.hno-heilkunde, ver.born.dt.gem.hno-heilkunde, verb.born.dt.gem.hno-heilkunde, verh.born.dt.germ.hno-heilkunde
verh.born.dt.gem.hno- » very.born.dt.gem.hno-, ver.born.dt.gem.hno-, verb.born.dt.gem.hno-, verh.born.dt.germ.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: (( vers.born.dt.ges.hno-heilkunde 11 ) OR ((( verh.born.dt.gem.hno-heilkunde 11 ) OR ( verh.born.dt.gem.hno-((heilkunde 5.1) OR (heilkunde 15.15)) )))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( vers.born.dt.ges.hno-heilkunde 11 ) or ((( verh.born.dt.gem.hno-heilkunde 11 ) or ( verh.born.dt.gem.hno-((heilkunde 5.1) OR (heilkunde 15.15)) ))))".
• Adding a wildcard symbol may retrieve word variants: (( vers.born.dt.ges.hno-heilkunde 11 ) or ((( verh.born.dt.gem.hno-heilkunde 11 ) or ( verh.born.dt.gem.hno-((heilkunde 5.1) OR (heilkunde 15.15)) ))))*.
