• Performing a fuzzy search may retrieve terms with similar spellings: "(rolf OR roof) ((henne" OR ((hennes" OR hannes") OR (hennas" OR henna"))) OR hence")~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"(rolf OR roof) ((henne\" OR ((hennes\" OR hannes\") OR (hennas\" OR henna\"))) OR hence\")".
• Removing quotes may allow a broader search: (rolf OR roof) ((henne OR ((hennes OR hannes ) OR (hennas OR henna ))) OR hence ).
• Adding a wildcard symbol may retrieve word variants: "(rolf OR roof) ((henne" OR ((hennes" OR hannes") OR (hennas" OR henna"))) OR hence")*.
