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