Perhaps you should try some spelling variations:
"robert risch" » "robert rich", "robert hirsch", "robert bosch"
"robert price" » "robert pringle", "robert payne", "robert pye"
"robert rise" » "robert rice", "robert rose", "robert rosen"

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