Perhaps you should try some spelling variations:
"verh.been.dt.gels.hno-heilkunde 15.15" » "verh.been.dt.gels.hno-heilkunde 5.1", "verh.been.dt.gets.hno-heilkunde 15.15", "verh.been.dt.geld.hno-heilkunde 15.15", "very.been.dt.gels.hno-heilkunde 15.15", "ver.been.dt.gels.hno-heilkunde 15.15", "verb.been.dt.gels.hno-heilkunde 15.15"
"vers.bern.dt.gels.hno-heilkunde 11" » "vers.bern.dt.gels.hno-heilkunde 1", "vers.bern.dt.gels.hno-heilkunde 10", "vers.bern.dt.gels.hno-heilkunde 16", "verse.bern.dt.gels.hno-heilkunde 11", "verso.bern.dt.gels.hno-heilkunde 11", "very.bern.dt.gels.hno-heilkunde 11", "vers.born.dt.gels.hno-heilkunde 11", "vers.ben.dt.gels.hno-heilkunde 11", "vers.bern.dt.gets.hno-heilkunde 11", "vers.bern.dt.geld.hno-heilkunde 11"
"vers.bern.dt.gel.hno-heilkunde 11" » "vers.bern.dt.gel.hno-heilkunde 1", "vers.bern.dt.gel.hno-heilkunde 10", "vers.bern.dt.gel.hno-heilkunde 16", "verse.bern.dt.gel.hno-heilkunde 11", "verso.bern.dt.gel.hno-heilkunde 11", "very.bern.dt.gel.hno-heilkunde 11", "vers.born.dt.gel.hno-heilkunde 11", "vers.ben.dt.gel.hno-heilkunde 11"

Try widening your search to All Fields.

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.bern.dt.gels.hno-heilkunde 11") OR ("vers.bern.dt.gel.hno-heilkunde 11"))) OR ("verh.been.dt.gels.hno-heilkunde 15.15")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"vers.bern.dt.gels.hno-heilkunde 11\") OR (\"vers.bern.dt.gel.hno-heilkunde 11\"))) or (\"verh.been.dt.gels.hno-heilkunde 15.15\"))".
• Removing quotes may allow a broader search: (((( vers.bern.dt.gels.hno-heilkunde 11 ) OR ( vers.bern.dt.gel.hno-heilkunde 11 ))) or ( verh.been.dt.gels.hno-heilkunde 15.15 )).
• Adding a wildcard symbol may retrieve word variants: (((("vers.bern.dt.gels.hno-heilkunde 11") OR ("vers.bern.dt.gel.hno-heilkunde 11"))) or ("verh.been.dt.gels.hno-heilkunde 15.15"))*.
