How do you search the WhoIs Database?

I am trying to figure out how to research the WhoIs database to see who how many domain names, and which ones, to which a person or entity is registered?

For example, I%26#039;m trying to figure out how many domain names are registered to John Doe. I%26#039;d like access to the WhoIs database so I can search for all sites that have the registrant John Doe and have a list returned to me.

I know I can enter a website, like www.OneMonthFree.com, into a domain registration firm like GoDaddy and use their WhoIs database to find out the registrant of a specific domain, but there are some 59 million .com sites and I really don%26#039;t have that much time. I want to reverse that process and research on name or address or phone number or other searchable field.

Naturally, I%26#039;d like to search for free, but pay sites are OK.
