Perhaps you should try some spelling variations:
heilkunde 11 » heilkunde 1, heilkunde 16, heilkunde 31
heilkunde 10 » heilkunde 1, heilkunde 16, heilkunde 40
heilkunde 18 » heilkunde 1, heilkunde 16, heilkunde 4.8
verh.bern.dt.gets.hno-heilkunde » ver.bern.dt.gets.hno-heilkunde, vers.bern.dt.gets.hno-heilkunde, verb.bern.dt.gets.hno-heilkunde, verh.ben.dt.gets.hno-heilkunde, verh.bern.dt.get.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- » very.born.dt.gel.hno-, very.born.dt.geld.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.gets.hno-heilkunde 11 ) OR ((( very.been.dt.gels.hno-heilkunde 11 ) OR ( very.born.dt.gels.hno-((heilkunde 10) OR (heilkunde 18)) )))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( verh.bern.dt.gets.hno-heilkunde 11 ) or ((( very.been.dt.gels.hno-heilkunde 11 ) or ( very.born.dt.gels.hno-((heilkunde 10) OR (heilkunde 18)) ))))".
• Adding a wildcard symbol may retrieve word variants: (( verh.bern.dt.gets.hno-heilkunde 11 ) or ((( very.been.dt.gels.hno-heilkunde 11 ) or ( very.born.dt.gels.hno-((heilkunde 10) OR (heilkunde 18)) ))))*.
