• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((heinrich OR hinrichs) OR enrich) ((heine\" OR (hine\" OR shine\")) OR hein\")".
• Removing quotes may allow a broader search: ((heinrich OR hinrichs) OR enrich) ((heine OR (hine OR shine )) OR hein ).
• Adding a wildcard symbol may retrieve word variants: "((heinrich OR hinrichs) OR enrich) ((heine" OR (hine" OR shine")) OR hein")*.
