• If you are trying to use Boolean operators, they must be ALL CAPS: (( luis a der transfer ((bei maria) OR (bei martin)) ) OR ( luis a heat transfer dau _ ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis a der transfer ((bei maria) OR (bei martin)) ) or ( luis a heat transfer dau _ ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis a der transfer ((bei maria) OR (bei martin)) ) or ( luis a heat transfer dau _ ))*.
