how can I lsearch for used domains which include a specific word?

[tankman1989]

Is there a program, app or site which will allow me to search for domains that include a specific word, like use a wildcard search? *iphone*? I would think Google would be able to do this but I am not sure how to find that .

Any ideas? Any suggestions are greatly appreciated!

Thanks
