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.born.dt.ges.hno-heilkunde OR vers.born.dt.ges.hno-heilkunde) OR verh.born.dt.gets.hno-heilkunde) 15.15 ) OR ( verh.born.dt.gems.hno-((heilkunde 15.15) OR (heilkunde 11)) )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((verh.born.dt.ges.hno-heilkunde or vers.born.dt.ges.hno-heilkunde) or verh.born.dt.gets.hno-heilkunde) 15.15 ) or ( verh.born.dt.gems.hno-((heilkunde 15.15) OR (heilkunde 11)) ))".
• Adding a wildcard symbol may retrieve word variants: (( ((verh.born.dt.ges.hno-heilkunde or vers.born.dt.ges.hno-heilkunde) or verh.born.dt.gets.hno-heilkunde) 15.15 ) or ( verh.born.dt.gems.hno-((heilkunde 15.15) OR (heilkunde 11)) ))*.
