• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"michael schwarz\") OR (((\"michal schwarzesen\") OR (\"michal schwarzesesen\"))))~".
• Removing quotes may allow a broader search: (( michael schwarz ) OR ((( michal schwarzesen ) OR ( michal schwarzesesen ))))~.
• Adding a wildcard symbol may retrieve word variants: (("michael schwarz") OR ((("michal schwarzesen") OR ("michal schwarzesesen"))))*.
