• Performing a fuzzy search may retrieve terms with similar spellings: "(heinrich OR enrich) ((heine" OR (veined" OR (reined" OR reigned"))) OR (hein" OR hin"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"(heinrich OR enrich) ((heine\" OR (veined\" OR (reined\" OR reigned\"))) OR (hein\" OR hin\"))".
• Removing quotes may allow a broader search: (heinrich OR enrich) ((heine OR (veined OR (reined OR reigned ))) OR (hein OR hin )).
• Adding a wildcard symbol may retrieve word variants: "(heinrich OR enrich) ((heine" OR (veined" OR (reined" OR reigned"))) OR (hein" OR hin"))*.
