Perhaps you should try some spelling variations:
"marcus roth a" » "marcus ruth a", "marcus foth a", "marc roth a", "marcus roth _", "marcus roth k"
"march 11th a" » "march 13th a", "march 14th a", "march 11 a", "march 11th ag", "march 11th _", "march 11th eai"
"march 11th day" » "march 13th day", "march 14th day", "march 11 day"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("marcus roth a") OR ((("march 11th a") OR ("march 11th day")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"marcus roth a\") or (((\"march 11th a\") OR (\"march 11th day\"))))".
• Removing quotes may allow a broader search: (( marcus roth a ) or ((( march 11th a ) OR ( march 11th day )))).
• Adding a wildcard symbol may retrieve word variants: (("marcus roth a") or ((("march 11th a") OR ("march 11th day"))))*.
