• If you are trying to use Boolean operators, they must be ALL CAPS: (((("very.bern.dt.geld.hno-heilkunde 10") OR ("everh.been.dt.geld.hno-heilkunde 1991"))) OR ("ver.bern.dt.gel.hno-heilkunde 15.15")).
• Removing quotes may allow a broader search: (((( very.bern.dt.geld.hno-heilkunde 10 ) or ( everh.been.dt.geld.hno-heilkunde 1991 ))) or ( ver.bern.dt.gel.hno-heilkunde 15.15 )).
• Adding a wildcard symbol may retrieve word variants: (((("very.bern.dt.geld.hno-heilkunde 10") or ("everh.been.dt.geld.hno-heilkunde 1991"))) or ("ver.bern.dt.gel.hno-heilkunde 15.15"))*.
