• Performing a fuzzy search may retrieve terms with similar spellings: "(das OR dank) ((leiner" OR (seiner" OR einer")) OR ((deines" OR meines") OR (sein" OR mein")))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"(das OR dank) ((leiner\" OR (seiner\" OR einer\")) OR ((deines\" OR meines\") OR (sein\" OR mein\")))".
• Removing quotes may allow a broader search: (das OR dank) ((leiner OR (seiner OR einer )) OR ((deines OR meines ) OR (sein OR mein ))).
• Adding a wildcard symbol may retrieve word variants: "(das OR dank) ((leiner" OR (seiner" OR einer")) OR ((deines" OR meines") OR (sein" OR mein")))*.
