• If you are trying to use Boolean operators, they must be ALL CAPS: ((doring christian) OR (von christian)) (nach OR (buch OR auch ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doring christian) OR (von christian)) (nach OR (buch OR auch ))~".
• Adding a wildcard symbol may retrieve word variants: ((doring christian) OR (von christian)) (nach OR (buch OR auch ))*.
