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: (((("verh.bern.dt.geld.hno-heilkunde 1991") OR ("verh.bern.dt.geld.hno-heilkunde 1"))) OR ((("vers.born.dt.gel.hno-heilkunde 11") OR ("vero.been.dt.gel.hno-heilkunde 15.15")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"verh.bern.dt.geld.hno-heilkunde 1991\") OR (\"verh.bern.dt.geld.hno-heilkunde 1\"))) or (((\"vers.born.dt.gel.hno-heilkunde 11\") or (\"vero.been.dt.gel.hno-heilkunde 15.15\"))))".
• Removing quotes may allow a broader search: (((( verh.bern.dt.geld.hno-heilkunde 1991 ) OR ( verh.bern.dt.geld.hno-heilkunde 1 ))) 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: (((("verh.bern.dt.geld.hno-heilkunde 1991") OR ("verh.bern.dt.geld.hno-heilkunde 1"))) or ((("vers.born.dt.gel.hno-heilkunde 11") or ("vero.been.dt.gel.hno-heilkunde 15.15"))))*.
