I investigated. Actually, the posts and threads are all there. It's just that the search index is still rebuilding, so you have to use google to find them.
Unfortunately the search server is also out of space since we had to use it as the contingency scraper while things were down, and still need to transfer the data off of it.
The integrity, existence, and backups of the posts and images is first priority and being shorthanded and lacking extra resources (and funding) to put files I can't say we have much time or people able to work on peripheral public facing services at the moment. It will be done in due time.
