• If you are trying to use Boolean operators, they must be ALL CAPS: ((weiter von) OR (wirken von)) siemens (rginge OR ((fing OR finge ) OR ing )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((weiter von) OR (wirken von)) siemens (rginge OR ((fing OR finge ) OR ing ))".
