Then cut and past your post into the thread "Search test part 2." which was created just after this one.
Then come back to this thread ( Part 1. ) and delete your post from this thread only.
I believe deleted posts are still visible when doing a search.
So this thread should just end up with a load of deleted posts that you can't normally see, but if you search by username, you can find said posts.
