Perhaps you should try some spelling variations:
"marcus foth a" » "marcus ruth a", "marcus 4th a", "marcus horeth a", "marcus forth a", "marcus both a", "marcus roth a"
"angus smith a" » "angela smith a", "marcus smith a"
"angus smith _" » "angela smith _", "marcus smith _"

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 foth a") OR ((("angus smith a") OR ("angus smith _")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"marcus foth a\") or (((\"angus smith a\") OR (\"angus smith _\"))))".
• Removing quotes may allow a broader search: (( marcus foth a ) or ((( angus smith a ) OR ( angus smith _ )))).
• Adding a wildcard symbol may retrieve word variants: (("marcus foth a") or ((("angus smith a") OR ("angus smith _"))))*.
