Perhaps you should try some spelling variations:
"bernhard lawrence" » "berger lawrence", "richard lawrence", "bergman lawrence"
"bernhard laurent" » "bernat laurent", "gerard laurent", "bernhard claussen"
"bernhard lauer" » "bernhard laum", "bernhard laums", "bernhard peter"

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