Perhaps you should try some spelling variations:
"thomas main" » "thomas mair", "thomas mai", "thomas martin"
"thomas mann" » "thomas mayn", "thomas mannsn", "thomas masonn", "thomas many", "thomas kann", "thomas ann"
"thomas man" » "thomas may", "thomas manns", "thomas mason"

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: (((("thomas mann") OR ("thomas man"))) OR ("thomas main")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"thomas mann\") OR (\"thomas man\"))) or (\"thomas main\"))".
• Removing quotes may allow a broader search: (((( thomas mann ) OR ( thomas man ))) or ( thomas main )).
• Adding a wildcard symbol may retrieve word variants: (((("thomas mann") OR ("thomas man"))) or ("thomas main"))*.
