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