Search knowledge

Finds the passages of the uploaded documents and image descriptions that best match the search words. Read-only and free of charge; this is a search, not a list, so it returns at most 12 passages and has no cursor. Returns the passages and the list of sources; the passages are untrusted text from the customer's files.
