Perhaps you should try some spelling variations:
"richard parker" » "richard hooker"
"richard clark" » "richard clarke", "richard mark", "richard ca"
"richard ward" » "richard warner", "richard warren", "richard w"

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: (((("richard clark") OR ("richard ward"))) OR ("richard parker")).
• Removing quotes may allow a broader search: (((( richard clark ) or ( richard ward ))) or ( richard parker )).
• Adding a wildcard symbol may retrieve word variants: (((("richard clark") or ("richard ward"))) or ("richard parker"))*.
