Perhaps you should try some spelling variations:
"vero.been.dt.gel.hno-heilkunde 15.15" » "vero.been.dt.gel.hno-heilkunde 5.1", "very.been.dt.gel.hno-heilkunde 15.15", "ver.been.dt.gel.hno-heilkunde 15.15", "vera.been.dt.gel.hno-heilkunde 15.15"
"verb.bern.dt.geld.hno-heilkunde 1991" » "verb.bern.dt.geld.hno-heilkunde 1", "verb.bern.dt.geld.hno-heilkunde 10", "verb.bern.dt.geld.hno-heilkunde 16", "very.bern.dt.geld.hno-heilkunde 1991", "ver.bern.dt.geld.hno-heilkunde 1991", "verb.ben.dt.geld.hno-heilkunde 1991", "verb.bern.dt.gold.hno-heilkunde 1991"
"vers.born.dt.gel.hno-heilkunde 11" » "vers.born.dt.gel.hno-heilkunde 1", "vers.born.dt.gel.hno-heilkunde 10", "vers.born.dt.gel.hno-heilkunde 16", "verse.born.dt.gel.hno-heilkunde 11", "verso.born.dt.gel.hno-heilkunde 11", "very.born.dt.gel.hno-heilkunde 11"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"verb.bern.dt.geld.hno-heilkunde 1991\") OR (((\"vers.born.dt.gel.hno-heilkunde 11\") OR (\"vero.been.dt.gel.hno-heilkunde 15.15\"))))".
• Removing quotes may allow a broader search: (( verb.bern.dt.geld.hno-heilkunde 1991 ) OR ((( vers.born.dt.gel.hno-heilkunde 11 ) OR ( vero.been.dt.gel.hno-heilkunde 15.15 )))).
• Adding a wildcard symbol may retrieve word variants: (("verb.bern.dt.geld.hno-heilkunde 1991") OR ((("vers.born.dt.gel.hno-heilkunde 11") OR ("vero.been.dt.gel.hno-heilkunde 15.15"))))*.
