Domain research tool for registered CCTLD ?

[iboughta.com]

Hello,

I am after a tool to tell me all the domains (in cctld) which are registered.

Domainsearch.com can tell me a bit but not working great. Furthermore, if I do a search for "book", I want the tool to tell me that book.us is registered BUT also booksale.mx, historybook.de...

Any one know such a tool please (combining all this)?

Thanks
