I've been thinking about the problem of what to do if the answer to a question is very different to the question itself in embedding space. The KB method sounds interesting and not something I thought about, you sort work on the "document side" I guess. I've also heard of HYDE, the works on the query side, you generate hypothetical answers instead to the user query and look for documents that are similar to the answer, if I've understood it correctly.
