• If you are trying to use Boolean operators, they must be ALL CAPS: (((("very.bern.dt.geld.hno-heilkunde 1") OR ("verh.been.dt.geld.hno-heilkunde 1991"))) OR ("verso.ben.dt.gel.hno-heilkunde 115.15")).
• Removing quotes may allow a broader search: (((( very.bern.dt.geld.hno-heilkunde 1 ) or ( verh.been.dt.geld.hno-heilkunde 1991 ))) or ( verso.ben.dt.gel.hno-heilkunde 115.15 )).
• Adding a wildcard symbol may retrieve word variants: (((("very.bern.dt.geld.hno-heilkunde 1") or ("verh.been.dt.geld.hno-heilkunde 1991"))) or ("verso.ben.dt.gel.hno-heilkunde 115.15"))*.
