Perhaps you should try some spelling variations:
"marcus smith a" » "markets smith a", "marcus 4th a", "marcus fritz a"
"marcus foth a" » "marcus ruth a", "marcus 4th a", "marcus horeth a", "marcus forth a", "marcus both a", "marcus roth a"
"angus smith _" » "angela 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 smith a") OR ("marcus foth a"))) OR ("angus smith _")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"marcus smith a\") OR (\"marcus foth a\"))) or (\"angus smith _\"))".
• Removing quotes may allow a broader search: (((( marcus smith a ) OR ( marcus foth a ))) or ( angus smith _ )).
• Adding a wildcard symbol may retrieve word variants: (((("marcus smith a") OR ("marcus foth a"))) or ("angus smith _"))*.
