Perhaps you should try some spelling variations:
"thomas manns" » "thomas mangey", "thomas manys", "thomas mans", "thomas kanns"
"thomas main" » "thomas mair", "thomas man", "thomas mai"
"thomas mann" » "thomas many", "thomas man", "thomas kann"

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 main") OR ("thomas mann"))) OR ("thomas manns")).
• Removing quotes may allow a broader search: (((( thomas main ) or ( thomas mann ))) or ( thomas manns )).
• Adding a wildcard symbol may retrieve word variants: (((("thomas main") or ("thomas mann"))) or ("thomas manns"))*.
