I have a plugin that I'm wanting to retire. It uses a very handy shortcode that we used in a few key places and those references I was able to find and convert over to a new shortcode that I wrote that's more specific to our needs.
However, I suspect I used this code in a few odd posts and now can't find any way to find those posts. The concern is that I'll remove the plugin and then break those posts.
How can I find out which posts contain those very specific shortcode references?
