Great suggestion. I had a LibrarianSearch app that would help with finding posts based various sorting criteria. I still have it, but currently it is not live. There wasn't much traffic to it, and I had stop paying heroku. I will need to restart it at some point.
I also have and app - https://hivelibrarian.herokuapp.com that can help with finding old conversations with other users. When I get a chance I will work on reactivating the post search one.
