Possibility of Regex Searches

[alt-glitch]

Is there a way to add grep type regex support to the tool? This would be really cool in finding out lateral subdomains like:
clientname1-example.com <-> example.com <-> clientname2-example.com

I'm aware that the data you're dealing with is quite large so I'm not sure how feasible it'd be for you. I'm happy to learn along and help.

Great work! Thanks

It is unlikely this will be possible due to the volume of the data, I would recommend downloading the data set yourself and grepping it. ripgrep can get through it in about 15-20 mins,
