This tool was shared by someone on X. It's defaulted to search through Superstonk right now, but you can see all the fields are easy to alter. When it shows "0" comments on a post, click the zero and it will show the comments as well.

This tool was used to pull up the Burger chain heat lamp theory post. Searching for heat lamp alone in Super, yielded many more posts around the subject, as an example of what it can do. This goes further than google cache can do.
