Perhaps you should try some spelling variations:
"robert rice" » "robert price", "robert rene", "robert rose"
"robert rich" » "robert price", "robert richard", "robert nichol"
"robert roe" » "robert rose", "robert ross", "robert rene"
"robert rae" » "robert rene", "robert r"

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