Perhaps you should try some spelling variations:
heilkunde 10 » heilkunde 11, heilkunde 16, heilkunde 18
heilkunde 1 » heilkunde 11, heilkunde 16, heilkunde 18
verb.bern.dt.geld.hno- » very.bern.dt.geld.hno-, ver.bern.dt.geld.hno-, verb.born.dt.geld.hno-, verb.bern.dt.gold.hno-
vera.ben.dt.geld.hno- » vera.ben.dt.gold.hno-, very.ben.dt.geld.hno-, ver.ben.dt.geld.hno-
vers.been.dt.gel.hno- » verse.been.dt.gel.hno-, verso.been.dt.gel.hno-, very.been.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: (((( verb.bern.dt.geld.hno-((heilkunde 1) OR (heilkunde 10))6991 ) OR ( vera.ben.dt.geld.hno-((heilkunde 1) OR (heilkunde 10)) ))) OR ( vers.been.dt.gel.hno-((heilkunde 1) OR (heilkunde 10))8 )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( verb.bern.dt.geld.hno-((heilkunde 1) OR (heilkunde 10))6991 ) or ( vera.ben.dt.geld.hno-((heilkunde 1) OR (heilkunde 10)) ))) or ( vers.been.dt.gel.hno-((heilkunde 1) OR (heilkunde 10))8 ))".
• Adding a wildcard symbol may retrieve word variants: (((( verb.bern.dt.geld.hno-((heilkunde 1) OR (heilkunde 10))6991 ) or ( vera.ben.dt.geld.hno-((heilkunde 1) OR (heilkunde 10)) ))) or ( vers.been.dt.gel.hno-((heilkunde 1) OR (heilkunde 10))8 ))*.
