• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"(gehrmann OR gehrmanns) politica\") OR (\"(gehrmann OR gehrmanns) (polnischen\" OR politischer\")))*".
• Removing quotes may allow a broader search: (( (gehrmann OR gehrmanns) politica ) OR ( (gehrmann OR gehrmanns) (polnischen OR politischer )))*.
