• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((gehrmann OR (german OR hermann)) OR ((germani OR germanii) OR germany)) (studien\" OR studie\")~".
• Removing quotes may allow a broader search: ((gehrmann OR (german OR hermann)) OR ((germani OR germanii) OR germany)) (studien OR studie )~.
• Adding a wildcard symbol may retrieve word variants: "((gehrmann OR (german OR hermann)) OR ((germani OR germanii) OR germany)) (studien" OR studie")*.
