Perhaps you should try some spelling variations:
"gerd schwartz" » "chern schwartz", "d schwartz", "mark schwartz"
"gary schwartz" » "barry schwartz", "mark schwartz", "mr schwartz"
"a schwartz" » "_ schwartz", "a schwarz", "l schwartz"

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