Not an expert; what I think jdpigeon is referring to, though, is that the information storage is just fine, even if the indexing mechanisms aren't. Like recovering data from a broken filesystem - the directory structure is lost and for a normal usecase the data might as well be gone, but a lot of the content is theoretically there and recoverable if some indexing system (even one different from the original) can be created.
